Capacitor charging time. Capacitor voltage when charging. When a capacitor is charged through a resistor, the voltage across it increases exponentially. Usually use the time constant of the RC circuit equal to τ = R * C, which determines the time during which the voltage across the capacitor becomes ~ 63.2% of the applied to the RC circuit.
