At time t=0, the switch is moved to position A and remains there for 2.00 seconds. Then the switch is moved to position B. Assume the battery and ammeter are ideal and the resistance of the wires is negligible. a) Find the charge on the capacitor after the switch was in position A for 2.00 seconds. R = 27.5 k A C = 47.0 μF (initially uncharged) + - B Switch position A ε = 12.0 V b) Find the current through the ammeter after the switch has been in position B for 1.00 second. c) How long does it take (after the switch is moved to position B) for the charge on the capacitor to decrease to 53.0 μC?

If yes, explain how they are connected and why the capacitors will not be damaged by the lower voltage rating. If no, explain why they cannot be used without damaging the capacitor.
