A source of 10∠0° V (amplitude, peak phasor) feeds a 4 Ω resistor in series to node X. Node X has an 8 Ω resistor in series with −j6 Ω to the return line, and a j5 Ω reactance in series from X to the load Z_{L}. Find (a) the load resistance and (b) the load reactance (with sign) of Z_{L} for maximum average power, both in Ω, and (c) that maximum power in W.
