In a series L_R circuit X_L = R and power factor of the circuit is P_1 . When capacitor with capacitance C such that X_L = X_C is put in series, the power factor becomes P_2 . Calculate P_1/P_2

The power factor of an L-R series circuit is 0.5 and that of a C-R series circuit is 0.2. If the elements (L, C and R) of the two circuit are joined in series and connected to the same ac source, the power factor of this circuit is found to be 1. The ratio of the resistance in the L-R circuit to the resistance in the C-R circuit is
