Interpretation:
The time it would take to discharge a 0.025 µF capacitor to 1% of its full charge through a resistance of 10 Mχ should be calculated.
Concept introduction:
The product of RC is referred to as time constant for the circuitand is a measure of the time required for a capacitor to chargeor discharge.
Capacitor is discharged to 1% of its full charge. Therefore, the value of charge at time ‘t’ can be related to the initial charge by following equation.
Time taken for the discharge of the capacitor can be calculated using following relationship;

Use this distribution as a model for time (in hours) to failure of solid insulating specimens subjected to AC voltage.
