The current i(t) shown in Fig. 6-6 passes through a 1-F capacitor. Find (a) v ac ,

The current i(t) shown in Fig. 6-6 passes through a 1-µF capacitor. Find

(a) v_ac, the voltage across the capacitor at t = 5k ms (k = 0, 1, 2, 3, …) and 

(b) The value of a constant current source Idc which can produce the same voltage across the above capacitor at t = 5k ms when applied at t > 0. Compare I_dc with 〈i(t)〉, the average of i(t) in Fig. 6-6, for a period of 5 ms after t > 0.
