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:
“I am to be broken. I am to be derided all my life. I am to be cast up and down among these men and women, with their twitching faces, with their lying tongues, like a cork on a rough sea. Like a ribbon of weed I am flung far every time the door opens.”
—Virginia Woolf (1882–1941)
“The constant abrasion and decay of our lives makes the soil of our future growth.”
—Henry David Thoreau (1817–1862)
