For the circuit with output impedance of 100 Ω- j20 Ω, how much power is delivered to a matched load if the voltage VS = 25 V rms?
A) 1.56 W
B) 6.25 W
C) 3.12 W
D) 12.5 W

The power delivered to a matched load is given by:P = (VS^2) / (4 * Ro)where VS is the voltage source and Ro is the output impedance.In this case, VS = 25 V rms and Ro = 100 Ω- j20 Ω.Therefore, the power delivered to the load is:P = (25^2) / (4 * 100) = 1.56 W
