capacitor energy and time constant calculator

the capacitance time constant represents the physical quantity of the response change speed during the transient process of the circuit. there is a time dimension. the smaller the circuit's time constant, 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), the unit of r is mω; (megaohm), the unit of time constant t is s (second).
