ACT/CheckPoint 1 Both switches are initially open, and the capacitor is uncharged. What is the current through the battery just after switch S 1 is closed? 2R 1) I b = 0 2) I b = E /(3R ) +-ε C R 3) I b = E /(2R) 4) I b = E /R I b +-+-S 2 S 1 Capacitor acts like a wire the instant the switch is instant the switch is closed: I /(2R) Physics 102 ...
