Rc circuit time constant

In this circuit the capacitor stores electric charge, and the resistor controls. So time constant is the duration in seconds during which the current through a capacities circuit becomes 36. Exactly how much time it takes to adjust is defined not only by the size of the capacitor , but also by the resistance of the circuit. Written by Willy McAllister.
