(b) What is die current through resistor R 2 when the capacitor is fully charged, long after die switch is closed? (c) What happens if the switch is opened after it has been closed for some rime? (d) If the switch has been closed for a time period long enough for the capacitor to become fully charged, and then the switch is opened, how long before the current through resistor R 1 reaches half of its initial value?

capacitance of 10 mF. The switch is closed and
after a long time the capacitor is fully charged.
(a) What is the current through each resistor a
long time after the switch is closed? (b) What is
the voltage across each resistor a long time after
the switch is closed? (c) What is the voltage

is closed? (d) What is the charge on the
capacitor a long time after the switch is closed?
(e) The switch is then opened. The capacitor
discharges through the resistors. How long from
the time before the current drops to one fifth of
the initial value?

(a) A 0.20-F capacitor is to be charged through a resistor so that it becomes 63 percent charged in 0.10 s. What should the resistance of the capacitor be? (b) What is the time constant if the capacitor is charged through a 20-MΩ resistor?
Consider a capacitor C that is fully charged by a 10 V power supply. Later on, the resistor R,
shown in the circuit, is connected across this fully charged capacitor. When the capacitor lost
50% of its stored energy, the current I (in A) - shown in the circuit- is:
R= 22
