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 time and/or constant:
“People who know what is good for other people all the time are as big a menace in our society as the capitalists.”
—May Hobbs (b. 1938)
“If ever thou shalt love,
In the sweet pangs of it remember me;
For such as I am, all true lovers are,
Unstaid and skittish in all motions else
Save in the constant image of the creature
That is beloved.”
