In an experiment to investigate the discharge of a capacitor through a resistor, the circuit shown below was setup. The battery has an EMF of 10V and negligible internal resistance. The switch was first closed, and the capacitor allowed to charge fully. The switch was then opened (at time t = 0) and the graph below shows how the millimeter reading subsequently changed with time. Using the graph below, Calculate the value of the resistance R. Estimate the charge stored on the capacitor at the start of the discharge process. Find the energy stored at the start of the discharge. Calculate the capacitance C, of the capacitor. What would be the effect on the shape of the graph if the value of R where increased.
