Unformatted text preview: V ) is connected to a resistor ( R ) at time t=0s . How long does it take for this capacitor to discharge 1/e of initial voltage? (note: e = 2.71828) 8. Draw a schematic diagram of series circuit consisting of an ac source, a resistor, a capacitor, and an inductor. If the ac source is operating at a frequency of 14.20 MHz, R = 20 , and C = 374 pF, determine the amount of inductance (L) that will produce a phase angle of 45 degrees. What is the magnitude of the impedance in this circuit?...
