connect 2 different wire gauge to pos and neg speaker terminal

Al (almarg),

1. What is the stuff that flows through a light bulb and comes back out again through the other wire?

The answer to question #1 is ELECTRIC CHARGE. Charge is a "stuff" that flows through lightbulbs, and it flows around a circuit. Normally no charge is lost during the operation of a circuit, and no charge is gained. Also, charge flows very slowly, and it can even stop flowing and just sit there inside the wires. In an AC circuit, charge does not flow forwards at all, instead it sits in one place and wiggles forwards and back.

Is this guy wrong?

Hi Jim,

As often occurs when this kind of subject comes up, ambiguity and/or imprecise use of terminology muddles the issue. If you replace his use of the word "charge" with the words "charge carrier," I think what he says then becomes pretty much correct.

As explained by Kijanki with the balls in a tube analogy, and as alluded to in my long post in this thread dated 8-23-2017 at 7:08 p.m. EDT (although what I said in that post was stated in terms signal energy rather than charge), charge propagates at near light speed, while charge carriers (electrons, in the case of a metallic conductor) move very slowly. And current, defined in terms of amperes, is proportional to the average number of charge carriers traversing a given cross-section of the conductor per unit time.

Best regards,

I'm still thinking about the question. 😛

Well that’s good isn’t it? At least you’re thinking about something other than photons .

Protons? That is SO funny! 😄 You get the Laughing Goat award for the funniest post of the weekend.
