The dielectric materials used in real capacitors are not perfect insulators. A resistance called a leakage resistance in parallel with the capacitance can model this imperfection. A 170-F capacitor is initially charged to 100 V

We want 83 percent of the initial energy to remain after one minute.

what is the limit on the leakage resistance for this capacitor?
