Question

What acts as positive and negative poles in a cell

Answer 1

Answer:

In a direct current (DC) circuit, current flows in one direction only, and one poleis always negative and the other pole is always positive. In an alternating current (AC) circuit the two poles alternate between negative and positive and the direction of the current (electron flow) reverses periodically.

thnks for asking ☺☺
