Question

question 12 of 25
in which circuit does charge reverse direction many times per second?
a. an ac circuit
b. a parallel circuit
c. a combined circuit
d. a dc circuit

Explanation:

AC (alternating - current) circuits have current (and thus charge) that reverses direction many times per second. In contrast, DC (direct - current) circuits have current flowing in one direction only. Parallel and combined circuits are about the arrangement of components, not the direction - changing nature of the current.

Answer:

A. An AC circuit
