Question: In the circuit shown, R = 5 0 k , V = 2 5 Volts, and C = 1 0 F . The capacitor is

In the circuit shown, R=50k,V=25 Volts, and C=10F. The capacitor is initially uncharged.
a) Calculate the time constant of the circuit.
b) Calculate the current in the circuit as soon as the switch is set to position A .
c) Calculate the voltage across the capacitor 1 second after the switch us set to position A .
d) The capacitor is allowed to fully charge. Then the switch is then set to position B, and the capacitor is allowed to discharge. Calculate how long it takes after the switch is set to B for the charge on the capacitor to reduce to one-fourth of the full charge?
In the circuit shown, R = 5 0 k , V = 2 5 Volts,
