|||Look at this circuit, where C1= \mu F , C2= \mu F , and
V= Volt . Both capacitors are uncharged.
C1 is first charged by closing switch S1. Then S1 is opened, and the charge capacitor is connected to C2 by closing S2.
Find the initial charge acquired by C1 when S1 is closed, and the final charges on C1 and C2 when S2 is closed.
