9. The current in an ac circuit containing only an ac voltage source and a 10-F capacitor
Question:
9. The current in an ac circuit containing only an ac voltage source and a 10-μF capacitor is described by I = (2.0 A) sin(120πt + π/2). Explain why the instantaneous voltage across it at t = 0 is zero whereas the current at that time is not.
