The resistor in an RC circuit has a resistance of 125 Ω. (a) Whatcapacitance must be used in this circuit if the time constant is to be4.5 ms? (b) Using the capacitance determined in part (a), calculatethe current in the circuit 9.0 ms after the switch is closed. Assumethat the capacitor is uncharged initially and that the emf of thebattery is 9.0 V.
