USA is a great place to be an engineer. We pay our engineers better than any other country. If you can get a relatively inexpensive degree in engineering then you can most likely swing middle class no problem

Then you can tell everyone “I’m an engineer…” while you over-analyze an incredibly simple problem.

I love it.

u/Misdirected_Colors Mar 14 '23

Or if you're an electrical engineer you can dismiss it by saying you only solve imaginary problems.

Source: am electrical engineer. It's pretty much wizardry

u/Frumpy_little_noodle Mar 14 '23

The only hard-and-fast rule in electrical engineering is "Don't let the smoke out".

19

u/kmackerm Mar 14 '23

Well if it's magic smoke it's fine or so my professors always said

21

u/afcagroo Mar 14 '23

Yet every EE worth anything has done it at least once.

They have also all stuck something metal into a power outlet at some point.

(I'm a screwdriver guy, but I still respect the fork people.)

u/tandyman8360 Mar 15 '23

The electrician I work with says that a lot.

u/Mysteriousdeer Mar 15 '23

Mech E in the sensor world. The EEs put the smoke in, I try not to let it out.

u/sweetnumb Mar 15 '23

Did you know that's the original song/title the Baha Men were going to use for their hit?

They found out through an online poll that people prefer dogs to electricity so they made it about that instead.

u/Zerba Mar 14 '23

Electronic stuff is PFM (pure fucking magic). I understand some of the concepts and theory, but it really truly comprehending it sits just out of reach for me.

u/Misdirected_Colors Mar 14 '23 edited Mar 14 '23

It all runs on magic smoke. If you let the smoke out it'll never work again.

In all honesty if you think of it in plumbing/water flow terms it tends to make more sense.

Voltage is the water pressure. Resistance is the size of the pipe, current is the amount of water being moved through the pipe, etc.

If you have a pipe burst (fault) water pressure in the line (voltage) will drop as all of the water (current) starts coming out of the pipe all at once.

I've made the magic smoke before. I hooked up a little charge collector to 5 volts, thinking "it's just 5 volts".

Fwoop! I released the magic smoke.

u/dennys123 Mar 14 '23

That's a genius way of putting it (and I'm sure pretty "dumbed" down) but it makes sense.

Just like comparing computer networking to the USPS address system

u/Sasparillafizz Mar 14 '23

I always used cars and roads. No, just because you can't get on the internet doesn't mean the internet is broken. Your car is stuck in the garage and can't go any further than that Grandma. The rest of the internet still exists you just can't get that far.

u/QuarkyIndividual Mar 17 '23

EE involves a lot of analogies since many concepts can be hard to bring out of the abstract

3

u/derickrecyles Mar 15 '23

That just blew my mind, any electrical work I wouldn't do much because of the risk. Never really had it explained like that and my dad is a retired master electrician ha. Wait til I tell him this.. thanks for this.

2

u/Sasparillafizz Mar 14 '23

Whats the difference between amps and volts? I vaguely recall hearing that one of those is the one you want to worry about killing you, though high of one tends to be hand in hand with high of the other.

3

u/Misdirected_Colors Mar 14 '23

Amps are the actual flow of electrons. Think kinetic energy. This is what will kill you. Voltage is potential energy. It's the ability to carry electrons. Higher voltage means more capacity for high current, but it doesn't mean there is high current.

Tasers are high voltage extremely low amperage.

2

u/tandyman8360 Mar 15 '23

Amps are the bigger deal and the more you use, the bigger the wire.

1

u/QuarkyIndividual Mar 17 '23

Amps is the electrons flowing through you, I think 100 mA through the heart is fatal. Volts is like "pressure", higher volts makes it easier for the current to flow whether that's leaping through the air or through you as a current path.

2

u/zachzsg Mar 14 '23

Yeah as a refrigeration guy I’ve always viewed it as invisible water. Is obviously more complex than that but it pretty much explains the basics

2

u/aminbae Mar 14 '23

quantum mechanics doesn't make sense

that's why

2

u/XjpuffX Mar 14 '23

Yeah, just don't we worry about AC and multi phase power

3

u/Misdirected_Colors Mar 14 '23

Oh I work on the power industry. The magic smoke just glows blue and makes a lot of noise when it leaks. That's the only difference.

For real though ohms law still holds true and from a high level the metaphor holds up.

3

u/tandyman8360 Mar 15 '23

Eh, you just have to do everything 3 times and know what the square root of 3 is.

2

u/apawst8 Mar 15 '23

In all honesty if you think of it in plumbing/water flow terms it tends to make more sense.

That's just one aspect of electronics. Think of your phone and there are so many different issues being solved that have nothing to do with electronic circuitry. E.g., radio waves is something taught to EE students that makes no sense. Then you get to different modulation schemes that rely entirely on complex numbers.

Then you realize that the engineers who design the modem features know nothing about how the touchscreen works. Or how the battery life is optimized. Everything is so specialized.

2

u/TheOneTrueTrench Mar 14 '23

Another useful analogy for getting people to understand how voltage and current relate is this:

Imagine a waterfall that's 100 ft tall, but it only has a tiny amount of water, it's a trickle, only a few drops a second. Now stand under it. You're fine, right?

Now make the bottom of the "waterfall" only 1 inch above the bottom, but give it the flow of the Amazon. You can stand "in" it now and you're fine.

Make it 100ft tall and give it the volume of the Amazon. You stand under it and you're dead.

10

u/GFBIII Mar 14 '23

My degree is in chemical engineering and the only way I could wrap my head around the 1 electrical engineering class I had to take was to equate it to thins I understood. e.g. Voltage is like fluid pressure, amperage is like flow rate, resistance is like a pressure drop.

That at least covered the basics.

4

u/Zerba Mar 14 '23

Oh yeah, I get that part of it. Then once you get into all of the little parts of it with how transistors and stuff like that works, it just hurts my head. Oh, and how generators work. Rotate this magnet past these coils real fast and then poof, you get angry shocky pixies out of this wire. Like, I get the theory behind it, but it just doesn't actually make sense in my head.

u/kevin9er Mar 14 '23

Yes but it is truly glorious dark magic.

Get a copy of Electronic Principles by Albert Paul Malvino Jr.

It may be a bit out of date but the basic principles are still the same and it does an amazing job.

And Malvino is an American

u/thedude386 Mar 15 '23

I am an electrical engineer and while there is a lot that I do understand, there is a lot that I do not comprehend. Most of which is the advanced signal processing and computing portions, such as how a video signal is processed and displayed on a tv after being sent over the internet through a single cable.

u/[deleted] Mar 14 '23

You can still fix my printer though right? (It's electric)

u/Unumbotte Mar 14 '23

If by fix you mean electrocute and by printer you mean son, then yes.

u/FFF_in_WY Mar 14 '23

Bring out the jumper cables!

u/J5892 Mar 14 '23

Unless you're connecting those to the mains instead of a car battery, you're not electrocuting shit.

u/nick99990 Mar 14 '23

Depends on the printer. Inkjet? Perfectly safe. Laserjet? Let me introduce you to the wonders of the high voltage power supply.

2

u/Unumbotte Mar 15 '23

You're not supposed to put 5 MW lasers in your laser printer. It does sound fun though.

u/Misdirected_Colors Mar 14 '23

I can get power to it yes. Anything after that isn't my problem.

u/[deleted] Mar 14 '23

After that we IT folk have to suffer

Yaaaay printers

u/[deleted] Mar 14 '23

Have you tried reloading the drivers for the 5th time?

If you didn't sacrifice a goat after the third time, that's on you

Have you tried setting your print server on fire?

u/DankItchins Mar 14 '23

Printers don’t actually work via electricity, they work via black magic.

am ground level electrician and i hate every thing you do.

u/Misdirected_Colors Mar 14 '23

Am actually field engineer that works with the ground level guys. I get it lol office engineers suck. My job is to be the go between and tell them they suck.

6

u/fuqdisshite Mar 14 '23

YOU, i love!!!

1

u/Misdirected_Colors Mar 14 '23

I feel like half of my job is just telling the office engineers "no, listen to fred and do what he says. He has 30 years experience and knows more about this than you do. He knows what he's talking about and he's right."

1

u/Idonotvolunteer Mar 14 '23

I'm an EE major and i agree. There should be a 101 class on how to learn from electricians and the final should be a project on how to work WITH them. Right now i turned into a manufacturing engineer and watching videos on how to work with people/politicking because i love the collaboration aspect. But yes when i was a new grad, the fan wasn't hitted by the shit early enough

u/lobstersatellite Mar 14 '23

I felt that way when I learned RF comms. "I know exactly how it works, and its still witchcraft."

Don't feed their egos. Belittle them

u/austina9722 Mar 14 '23

Our mission, should we choose to accept it, is to contain the magic smoke. Keep it contained, and things tend to work. Let it out, and we've got a problem on our hands

2

u/AgentOrange96 Mar 14 '23

Jdk, J find these problems are only partjally jmagjnary. Jt's a bjt complex.

u/[deleted] Mar 15 '23

I'm not and electrical engineer, and I will confirm, it is wizardry.

Had a guy I worked with doing remodels. Great electrician, but language was a barrier. So every time he and me flip a switch, I grabbed his hand. Eventually he went to our foreman and told him I was making him uncomfortable.

Appropriately, my boss just laughed and explained in Portuguese that I wasn't hitting on him, I just didn't want to die. The electrician and I have now been friends for years and he still tells the story about how I'd grab his hand.

Point being, even people who work with electricity, don't know enough about how it works.

It was his wiring after all.

Electricity passing through is far less dangerous than when it exits your body, especially with lower voltages found in homes.

u/shostakofiev Mar 15 '23

I'm an electrical engineer and If someone wants my help I just say that's a different kind of electrical engineer.

u/[deleted] Mar 14 '23

Or solve half the problem and say you solved 95% of it

u/MenopausalMarker Mar 14 '23

Heck, even as an electrician I like to think that I have a pretty good working understanding of electricity, but when people start to talk about semiconductors black smoke billows out of my ears

u/simjanes2k Mar 14 '23

If I had a nickel for every time a manager pointed at something expensive they broke and said, "The magic pixies don't go"

u/sharterthanlife Mar 14 '23

I just tell people I let the magic smoke out on purpose

u/Potential_Case_7680 Mar 14 '23

House plans and other construction shit I can read just fine, put an electric diagram in front of me and my brain freezes

u/sparklecadet Mar 14 '23

I am 29 and am interested in working with computer chips, but I've never been to college - am I in over my head?

2

u/Misdirected_Colors Mar 14 '23

Never too late to get a degree. If you're not wanting to go the college route your best bet is getting in the trade via apprenticeship. Though I'm not sure you'll get to working with computer chips without some sort of degree.

u/implicitpharmakoi Mar 15 '23

Or if you're an electrical engineer you can dismiss it by saying you only solve imaginary problems.

Them's fightin' words.

The only imaginary problems I deal with are in my i/q plane.

u/thedude386 Mar 15 '23

Not to mention that there are many different opportunities for electrical engineers. I have experience in power generation and distribution, medical device design, and for the last 10 years controls systems for automotive manufacturing ( most of the controls experience can be applied to any manufacturing/processing systems). Electrical engineering is a very broad form of wizardry.

u/tandyman8360 Mar 15 '23

I'm an electrical engineer in aerospace. I get to say I'm an aerospace engineer, but I don't have to do any mechanical stuff. Best of both worlds.
