Question 1

[Maximum number: 3]

The variation with potential difference V of the charge Q on one of the plates of a capacitor is shown in Fig. 5.1.

The resistance of R is 25kΩ25 \mathrm{k} \Omega and the resistance of S is 220kΩ220 \mathrm{k} \Omega.
The switch can be in either position X or position Y .

The switch is in position X so that the capacitor is fully charged.

Calculate the energy E stored in the capacitor.
