If the circuit has a resistance of 15 Ω, now it is LCR series resonant circuit. Now the impedance, Z = $\sqrt{R^2+(X_L-X_C)^2}$ Z = $\sqrt{15^2+(27.93)^2}$ = 31.7 Ω Virtual current, $I_v$ = $\frac{E_v}{Z}$ = $\frac{230}{31.7}$ = 7.26 A Average power transferred to ‘L’, $P_L$ = $I_v E_v$ cos π/2 = 0 Average power transferred to ‘C’, $P_C$ = $E_vI_v$ cos π/2 = 0 Average power transferred to ‘R’, $P_R$ = $V_RI_v$ cos 0° $P_R$ = $(I_v R) I_v$ = $I_v^2$ R = (7.26)2 × 15 = 791 W
