alleryIn a circuit containing an inductor, the current does what relative to the voltage?
AIt links around
BIt lags behind
CIt leaps ahead
DIt leans across
Answer & Solution
Correct answer: B. It lags behind
1. An inductor opposes any change in the current through it.
2. The current therefore takes time to build up.
3. In the case of an inductor, the current lags the voltage by pi over two.
4. So the current lags behind.
