57. The Thévenin equivalent of a two-terminal
network is shown in Figure P5.87. The fre-
quency is f = 60 Hz. We wish to connect a
load across terminals a-b that consists of a
resistance and a capacitance in parallel such
that the power delivered to the resistance is
maximized. Find the value of the resistance
and the value of the capacitance.
