Find the current fort>O in a series RC circuit where R = 20nc =
0.005 F and E = 60sin30t V. Assume that when the switch is closed at t =
0. the charge on the capacitor is -0.03 C.*
i = 0.03 sin 30t - 0.09 cos 30t + 0.06e 101
i = 0.9 cos 30t + 2.7 sin 30t – 0.6
Option 1
Option 2
i = 2.7 cos 30t + 0.9 sin 30t - 0.6e 104
i = 0.09 sin 30t – 0.03 cos 30t + 0.00
