Electricity Poll: which way were you taught?

In summary, the conversation discusses the direction of electricity flow and how it is taught in different locations and schools. Some were taught that electricity flows from negative to positive, while others were taught the opposite. The concept of conventional current and electron flow was also mentioned, with some schools teaching both and others only teaching one. The discussion also touches on the history of this topic and the use of positive and negative notation in designating charges. Overall, the conversation highlights the various ways in which electricity flow is taught and understood.

The real question is, do you use ohms or mhos?

Reminds me of an old joke I just made up. Have you ever heard an electrical engineer meditating? "Ohhhhhhhm, Ohhhhhhhm, Ohhhhhhhm..."

The thread has a massive capacity farad lot of trolling.

We'll oppose a resistance to being rectified.

mhos = Siemens = 1/ohm

I believe we have a new induction into the "classic thread" forum.

It might even happen automatically, through self-inductance.

I feel everyone is so charged up with troll energy here.
Maybe we just need a bit of time to Coulomb down a bit.

Absolutely. Battery terminals should be labelled Affirmative and Negative IMO.

please calculate the charge/mass ratio of an affirmatron...

Yeah, I don't want any static!

[Note: this should only be considered a potential joke]

The whole thread has me polarized.

I remember waaaay back that it was necessary to polarize the generator on a positive grounded vehicle whenever the generator or voltage regulator was replaced.

The old mechanic who taught me how to do it said it was necessary in order to get the current worms moving in the right direction.:wink:

I teach students simultaneously that "current" is from + to - , while electrons (which are the only things flowing in solid conductors) drift from - to + .

(I want to go back in time so I could ask "Are you sure?"

and he would reply

"Yes, positive.")

Yet nevertheless, franklin, he was in lightning.

That brings back memories when I was way young.

Yes, I'm amazed so many are electrified by the current trend in humor.

And we have done it all with no shorts.

I don't believe in shorts, just heating elements.

If that's a circuitous way of saying you post naked then, paradoxically, those who post well insulated are the same ones who have the most shorts.

OOps I had a close call with continuity on that last phase.

I was immediately told both sides at the same time. Basically, I was told that electrons move from negative to positive; but because of the unfortunate convention, an electron is like a ''negative unit'' of current, so current goes from positive to negative.

I don't see how it can be taught in any other way without misleading people.

In high school I also learned how long it took for the electrons to move from the light switch to the light bulb, like other people in the thread.

Don't the lights in most people's houses run on AC?
