The circuit shown contains a voltage source with emf e = 8.99 V, a resistor with resistance R = 165 k2, and a capacitor with capacitance C= 647 nF. When switch S is set to position a, the three circuit elements are in series. When the switch is in position b, the battery is excluded from the circuit. The switch is initially moved to position a where it remains for a sufficiently long time that the capacitor is fully charged. Part (a) Calculate the maximum charge, in coulombs, on the capacitor.
