In the circuit diagram below, the capacitor C is first fully charged by using a 6.0V battery and the two way switch k. It is then discharged through the resistor R. The figure below shows how the charge Q on the capacitor C changes with time during the discharge. Use the graph to answer the following questions: What is the capacitance of the capacitor? Estimate the initial current through the resistor during the discharging process, hence, calculate the resistance of the resistor and the time constant of the circuit. On the same axes, draw graphs to show how the voltage Vc across the capacitor and VR across the resistor vary with time during the charging
