Question

a) What is in volts, the voltage across the capacitor the minute it is fully charged?

b) What is in volts, the voltage across the resistor the minute the capacitor is fully charged?

After a full charge, S1was opened and S2 was closed.

c) What is in seconds, the discharge time constant for the circuit?

d) How much charge remains in the capacitor after a discharge time of ?? Answer in units of micro-Coulombs.

e) What is the current through the capacitor at t=? after S2 was closed? Answer in units of micro-Amperes.

part a)

Voltage when it is fully cahrged=V

part b)

voltage acroos resisitor=0

when capacitor is fully charegd

part c)

discharge time constant=RC

part d)

after time constant voltage will remain V/e

Q=CV/e

part e)

when S2 is closed

I=V/(1/wC)
