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:
“The President has paid dear for his White House. It has commonly cost him all his peace, and the best of his manly attributes. To preserve for a short time so conspicuous an appearance before the world, he is content to eat dust before the real masters who stand erect behind the throne.”
—Ralph Waldo Emerson (1803–1882)
“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)
