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. θ t = 1 100 × θ 0 θ t = charge after discharge of the capacitor θ 0 = initial charge of the capacitor Time taken for the discharge of the capacitor can be calculated using following relationship; θ t = θ 0 e − t / R CStart your trial now!
