The time it takes for a capacitor to charge or discharge is characterized by the time constant (τ), defined as: \[ τ = R \times C \] where R is the resistance in the circuit. The time constant indicates how quickly a capacitor can charge to approximately 63% of the supply voltage or discharge to about 37% of its initial voltage. This principle is particularly important in RC (resistor-capacitor) circuits, which are widely used in timing applications. IV.
