A VERY VERY Basic Primer on Electricity

The flux capacitor has 1.21 jiggawatts ,but I use 220 221 whatever it takes.

The most complicated pressure cooker on the planet that works off black magic, voodoo, fast neutrons, boron, xenon, and some fancy metal rods.

Cherenkov radiation, aka the forbidden night light, is super cool. I think it's the best "sci-fi" part of nuke power. After the primary loop it's pretty much your plain Jane steam powered turbines.

everyone on this thread after the next twenty posts …

I resemble this remark!!

"It's not the volts that will kill you. It's the amps".

The one thing that stuck with me from my electronics class.

Oh, now I get it. A picture is truly worth 1000 words.

Question?
What are the inner workings for a DC Diode?
I know what it does but how does it do it?
EX: A hydraulic check valve allows flow in one direction by using a valve that seals flow in one direction but allows flow in another.
A compensating CK allows flow in both directions just not equal pressure by using a spring/or varying area spool, that the pressure has to over come to flow in the restricted direction.

SO !!! where is the light switch at !

And impedance (Z) in series and in parallel, and inductive and capactive reactance (X), and inductance (Henrys, the best unit name). AC is a whole 'nother beast...

Late to the party, I have a stack of these and pass them out to the apprentices on jobs. From houses to high rises. Space shuttle launch pads, precious metal mines, coal burners, nukes, solar & steam.
From a 9 volt to a lightning bolt, I've done it all.

What's all the trouble ?
Just lookup Maxwell's Equations

Everything else is intuitively obvious

Would rather use the smith chart for impedance matching, Maxwell is too mathy lol:

What started out as a simple electrical explanation thread turned into all the elec experts showing up to say “my dick is bigger than yours”. Lol. Everyone gotta speak what they know and confuse everyone else.

I can still hear my dad saying that exact line.

You have to admit it has been fun to watch.

Yeah, interesting comparison w hydraulic check valves

Lookup PN Junction Diode under Semiconductor Electronics. You can prob find great explanations online

in a semiconductor material like Silicon, a diode electrical action can happen when you have P-type and N-type regions adjacent to each other

Pure Silicon is a very poor conductor of electricity. The magic starts when you throw-in P-type or N-type ' dopant ' atoms into the Silicon lattice. Adding a dopant of just one part per Million can make the Silicon material a Million times more conductive. P-type dopant atoms like Boron are missing a valence electron compared w Silicon. N-type dopant atoms like Phosphorus have an extra valence electron

And the real semiconductor electronic magic happens when you have these P-type and N-type regions side by side


PN Junction Diode with No Voltage applied ( aka Zero Bias )

Forward Bias Voltage - Large Forward Current

Reverse Bias Voltage - Very Small Reverse Current

Thanks.
Hydraulics is easy to visualize, electricity not so much.
At least not for me.

Good electrical video here, pay attention!


Here's a good electrical diagram to study:

Finally, in closing, V x I does not equal Watts. Sorry. It might, if we're talking DC or unity power factor, but usually doesn't. V x I equals .... wait for it ...... Volt-amperes.

That video is worth every minute invested!!!
