(C) The impedance of an $LR$ circuit is given by $Z_{LR} = \sqrt{R^2 + X_L^2}$.When a capacitor is connected in series,the circuit becomes an $LCR$ circuit.The impedance of an $LCR$ circuit is given by $Z_{LCR} = \sqrt{R^2 + (X_L - X_C)^2}$.Since $(X_L - X_C)^2 According to Ohm's law for $AC$ circuits,$I = \frac{V}{Z}$.Since $I \propto \frac{1}{Z}$,a decrease in impedance $Z$ leads to an increase in the alternating current $I$ flowing through the circuit.

When a capacitor is connected in series to an $LR$ circuit,the alternating current flowing in the circuit
