The current entering the upper terminal is
i=24 cos 4000t A
Assume the charge at the upper terminal is zero at the instant the currentis passing through its maximum value. Find the expression for q(t).
The current through a given circuit element is given by i(t) = 2 e−t A. Find the net charge that passes through the element in the interval from t = 0 to t = ∞ [Hint:Current is the rate of flow of charge. Thus, to find charge, we must integrate current with respectto time.]
