The **RC time constant**, the time constant (in seconds) of an RC circuit, is equal to the product of the circuit resistance (in ohms) and the circuit capacitance (in farads), i.e. = *R × C*.

It is the time required to charge or discharge the capacitor, through the resistor, by 0.632 Vo(≈ 63.2) percent of the difference between the initial value and final value. This value is derived from the mathematical constant *e*, specifically .

### Famous quotes containing the words constant and/or time:

“We can never establish with certainty what part of our relations with others is the result of our emotions—love, antipathy, charity, or malice—and what part is predetermined by the *constant* power play among individuals.”

—Milan Kundera (b. 1929)

“Old hippies don’t die, they just lie low until the laughter stops and their *time* comes round again.”

—Joseph Gallivan (b. 1964)
