Charging capacitor Phys. 102, Lecture 7, Slide 5 + ε I R S 1 C S 2 Initially the capacitor is uncharged (Q0 = 0) At t = 0 we close switch S 1. Immediately after: Current I 0 flows around loop, through C No charge on C (Q 0 = 0) After a long time (t = ): Charge on C builds until V C = ε. Current decreases to zero (I = 0)
