3. In the circuit shown below, C=3.0 mF and the voltage of the battery is 10 V. 2.0 s after the switch is closed, the voltage across the resistor is 5.0 V. e) What is the resistance of the resistor? f) How long after the switch is closed will the voltage across the resistor be 2.5 V? g) Sketch a graph of the voltage across the resistor as a function of time, and the voltage across the capacitors as a function of time.
