In the circuit in Fig. 11.25, the 60-Ω resistor absorbs an average power of 240 W. Find V and the complex power of each branch of the circuit. What is the overall complex power of the circuit? (Assume the current through the 60-Ω resistor has no phase shift.)

Answer :  ; the 20- Ω resistor: 656 VA; the (30 -j10)Ω  impedance: 480 -j160 VA; the (60 + j20) Ω impedance: 240 + j80VA; overall: 1376 -j80 VA
