An RC circuit includes a 2-k N resistor, a battery with emf of 12.0 V and a capacitor. At t = 0 the switch is closed, and the charging of the capacitor begins. Knowing that the time constant of the circuit is measured to be 1 ms calculate: (a) the capacitance of the capacitor; (b) the time it takes for the voltage across the resistor to reach 4 V, and (c) the charge accumulated on the capacitor during this time interval.
