Same current is flowing in two alternating circuits. The first circuit contains only inductances and the other contains only a capacitor, if the frequency of the e.m.f of AC is increased, the effect on the value of the current will beA. increase in first circuit and decrease in secondB. increase in both circuitsC. decrease in both circuitsD. decrease in first circuit and increase in second |

Answer» Correct Answer - c Current corresponding to inductive circuit `I=(V)/(Z)=(V)/(omegaL) rarr I_("inductive") prop (1)/(omega)` similary for capocitive circuit wgeb frequency of AC is increased from Eq (i) `I_("inductive")` decrease abd from Eq (ii) `I_("capactive")` increases |
