Theoretical time constant
The time constant is related to the cutoff frequency fc, an alternative parameter of the RC circuit, by or, equivalently, where resistance in ohms and capacitance in farads yields the time constant in seconds or the cutoff frequency in Hz. Short conditional equations using the value for : WebbOne simple solution would be to say that a time constant will equal the time it takes for V C to reach half the supply voltage. This would work but then the formula for T would not …

Webb24 feb. 2012 · The time constant can be defined as the time it takes for the step response to rise up to 63% or 0.63 of its final value. We refer to this as t = 1/a. If we take reciprocal of time constant, its unit is 1/seconds or frequency. We call the parameter “a” the exponential frequency. Because the derivative of e-at is -a at t = 0.
