# Compound alternating current circuits

### Question 7 of 13

A coil takes a current of 5A when connected to a 15V DC supply. When connected to a 15V AC supply, the current is 3A. This difference in current is because, when connected to the DC supply, the

1. coil reactance is zero
2. coil resistance is zero
3. coil reactance is infinitely high
4. coil resistance is infinitely high
