The capacitor model we have used so far has beentreated as an ideal circuit element. A more accuratemodel for a capacitor is shown in Figure P4.67. Theideal capacitor, C, has a large “leakage” resistance, RC,in parallel with it. RC models the leakage currentthrough the capacitor. R1 and R2 represent the leadwire resistances, and L1 and L2 represent the lead wireinductances.a. If C = 1 μF, RC = 100 MΩ, R1 = R2 = 1 μΩ andL1 = L2 = 0.1 μH, find the equivalent impedanceseen at the terminals a and b as a function offrequency ω.b. Find the range of frequencies for which Zab iscapacitive, i.e., Xab > 10|Rab.Hint: Assume that RC is is much greater than 1/wC so thatyou can replace RC by an infinite resistance in part b.
Determine expressions for and sketch v R ( t ) to scale versus time for the circuit of Figure P4.43. The circuit is operating in steady state with the switch closed prior to t=0. Consider the time interval −1≤t≤5 ms.
Consider the circuit of Figure P4.17, in which the switch instantaneously moves back and forth between contacts A and B, spending 2 seconds in each position. Thus, the capacitor repeatedly charges for 2 seconds and then discharges for 2 seconds. Assume that v C ( 0 )=0 and that the switch moves to position A at t=0. Determine v C ( 2 ), v C ( 4 ), v C ( 6 ), and v C ( 8 ).
