Capacitor Energy and Time Constant Calculator

The capacitance time constant represents the physical quantity of the speed of response change during the transient process of the circuit. Has a time dimension. The smaller the time constant of the circuit, the faster its response changes, and vice versa.

The time constant is the product CR of resistance and capacitance. If the unit of C is μF (microfarad) and the unit of R is MΩ (megaohm), the unit of the time constant T is s (second).
