CR time constant
And the value of CR depends solely on the values of capacitor and resistor in this particular circuit. CR is known as the circuit''s time constant. For example, if C is 10 μF and R is 1 MΩ, the time constant is 10 seconds. Microfarads times megohms equals seconds. After a time equal to CR - one time constant - the capacitor has charged to 63%.
