# Applying Electron Flow Theory to Alternating Current

I am a beginner to electronics, so please excuse my ignorance. I have been searching endlessly for an explanation, but nothing I have read has fully answered my question.

Am I correct to say that in AC the hot wire and neutral wire fluctuate between positive and negative at a rate of $$60 hertz$$ (North American talking here)?

I could accept that, but my understanding from electron flow is that the positive is the return path and has voltage on it because it has the highest potential. The electrons flow out of the negative side and it has $$0V$$ because it has the lowest potential.

In AC, the neutral is always the return path. How can both be true at the same time? If neutral is always return, to me that would imply it is always positive. However, if neutral is the reference point with the least potential, then doesn’t that imply that neutral is always negative? It just doesn’t make sense to me.

• Do you know that current flows in the opposite direction of electrons? i.e., electron flows from the negative end to positive end while, the current flows from the positive to negative.

• Isn't that the conventional current theory? I thought it was incorrect but was used anyway. Jan 20 at 6:27
