1. A non-ideal capacitor having a ‘leaky’ dielectric where RL =1.5 x1015 which is the leakage resistance measured across the dielectric. A100 pF parallel-plate capacitor has a mica dielectric of relative permittivity år = 12 and resistivity of ñ = 1014 Ù m.
The capacitor holds a charge of 10 nC.. Estimate the time for the capacitor to completely discharge when left on open circuit and the total energy dissipated in the dielectric during
discharge.
