Find the equivalent impedance ZL shown in Figure P4.66(a), as seen by the source, if the frequency is 377 rad/s.
b. If we wanted the source to see the load as completely resistive, what value of capacitance should we place between the terminals a and b as shown in Figure P4.66(b)? Hint: Find an expression for the equivalent impedance ZL, and then find C so that the phase angle of the impedance is zero.
wire resistances, and L1 and L2 represent the lead wire inductances.
a. If C = 1 μF, RC = 100 MQ, R1 = R2 = 1 μQ and L1 = L2 = 0.1 μH, find the equivalent impedance seen at the terminals a and b as a function of
b. Find the range of frequencies for which Zab is capacitive, i.e., Xab > 10|Rab.
Hint: Assume that RC is is much greater than 1/wC so that you can replace RC by an infinite resistance in part b.
