Consider the circuit below. The capacitor has a capacitance of 21 mF and starts out uncharged. The switch is closed at time t = 0. R1 = 2 N R3 = 3 N V = 12 V R2 = 4 N R4 = 3 N a. At time t = 0 (immediately after the switch is closed), what is the current flowing out from the battery? Hint for (a) At time t = 0, the current from the battery А. b. A long time after the switch is closed (and capacitor is fully charged), what is the current flowing out from the battery? Hint for (b) A long time after the switch is closed, the current from the battery is А. c. What is the charge on the capacitor a long time after the switch is closed? Hint for (c) The charge on the capacitor a long time after the switch is closed is mC.
