A certain parallel-plate capacitor, which has one plate rotating so the overlap of the plates is a function of time, has a capacitance given by C = 200 + 50 sin(5000t) pF in which the argument of the cosine function is in radians. A constant voltage of 50V is applied to this capacitor. Determine the current as a function of time.
