Exercise 77

The current in a conductor varies in time as shown in Figure P17.58. (a) How many coulombs of charge pass through a cross section of the conductor in the interval from t = 0 to t = 5.0 s (b) What constant current would transport the same total charge during the 5.0-s interval as does the actual current
