1.

Prove that the current flowing through an ideal inductor connected across a.c. source lags behind the voltage in phase by pi/2.

Answer»

SOLUTION :Show as in Short Answer Question Number 2 above that for V = V, sin ot, the current `I = I_(m) sin (omegat - pi/2)` This proves that the current flowing through an ideal INDUCTOR LAGS behind an a.c. VOLTAGE in phase by `pi/2`.
