Fig. show three alternating circuits with equal currents. If frequency of alt. e.m.f be increased, what will be the effect on currents in the three cases? Explain.

Text Solution

Verified by Experts

(i) No effect, R is not affected by frequency.
(ii) Current will decrease as `X_L` increase.
(iii) Current will increase as `X_C` decrease.
