Question

8.46 The generator circuit shown in Fig. P8.46 (on page 494) is
connected to a distant load via a long coaxial transmission line.
The overall circuit can be modeled as in Fig. P8.46(b), in which
the transmission line is represented by an equivalent impedance
Zline = (5+ j2) W.
(a) Determine the power factor of voltage source Vs.
(b) Specify the capacitance of a shunt capacitor C that would
raise the power factor of the source to unity when connected
between terminals (a,b). The source frequency is 1.5 kHz.
