Question

The current and the potential difference in an inductor are in phase. B. The current lags the potential difference by π/2 in an inductor C. The current leads the potential difference by π/2 in an inductor. D. none of the above

Answer 1

Answer:

The current lags the potential difference by π/2 in an inductor

Explanation:

The potential difference leads to the current by  $\frac{\pi}{2}$. Alternate signals such as current and voltage -in this case- are periodic, this means that this signals are repeated at fixed spaces of time. Thus, In an inductor the current lags the potential difference by $\frac{\pi}{2}$.
