Exercise 33

Consider a series RC circuit as in Figure P18.33 for which R = 1.00 M , C = 5.00 µ F, and = 30.0 V. Find (a) the time constant of the circuit and (b) the maximum charge on the capacitor after the switch is thrown closed. (c) Find the current in the resistor 10.0 s after the switch is closed.
