Determine vc(t) for t > 0. The voltage across the capacitor in Figure P5.32 (attached file) just before the switch is changed as shown in the attached file. vc(0-) = -7 V Io = 17 mA C = 0.55 μF R1 = 7 kΩ R2 = 3.3 kΩ
a) Calculate the capacitive reactance XC, with C= 1μF and R= 200 Ohms for various frequencies and tabulate the values in Table 1 (see attached file). b) Plot f vs XC and comment on the plot. Compare this plot with another plot of f vs R. c) Calculate the phase angle (θ) for the RC circuit with C = 1μF and R= ...continues
