For DC (direct current). Make that AC and real-world interactions between resistive and reactive (capacitive and inductive) loads, and it gets really interesting and quite lucrative.
Yep. dV/dT or dI/dT can get really fun when you chuck it into Ohm’s wheel !
And then there’s KVL and KCL and for added fun there’s Diff Eq thrown in for signal analysis, although FFT is pretty darn cool.
AAAAARG! The Math, The Math!!
You have to know the phase angle between the current and voltage to be able to apply all that to AC current.
OK wise guys. Now explain three phase power transmission.
I did manage to squeak through differential equations, but that was half a century ago, and never applied since. Now I’m lucky to puzzle out the trailer lights in a 12v dc system.
All I remember the three phases were 120 degrees in rotation to each other…
You remember correctly.
So now you’re advocating math? Huh.
I had a disc that had TOIT on one side and the Ohm’s law pie chart above on the other. I got it in week 2 of Basic Electronics in the Air Force.
I got talked to by my Squadron Commander when I told the GS-12 that was teaching us Electronics that a transistor was NOT a voltage-controlled device, but a Current-Controlled device. I was prepared to back it up with some pretty solid Physics knowledge, but my SC told me to shut up and sit down. I was a lowly Airman and the Instructor Could Do NO Wrong!
Oy!
I’ve used plumbing to explain DC to people. It’s a good analog…
I tell people people, Plumbing, electricity(AC/DC) and the human body are analogous
It is indeed
Voltage – pressure
Current = flow
resistance = size of pipe/pressure regulator
watts – volume/amount of water.
KISS, baby!
You are not an electrician dammit
Cederq is also engaging in the cruelty of making us use math.
I need a drink.
Beer, more beer.
I definitely neglected electrical engineering. Don’t suppose there is any point learning it now.
You guys just could not resist posting this stuff, could you? Sentence if guilty should be a weak in a faraday cage, unless current conditions change. Another way to say it would be you guys have a lot of potential!
