A circuit operating in the sinusoidal steady state has two exposed terminals a and b. The phasor voltage Vab in the circuit is 480 /0° V (rms) when no external load is connected to terminals a,b. When a load having an impedance of 100 j0 Ω is connected across a,b, the value of Vab is 252.9822 /-18.3449° V (rms).
a) Find the impedance that should be connected across a,b for maximum average power transfer.
b) Find the maximum average power transfer to the load of (a).
