The Time Constant Calculator calculates the time constant for either an RC (resistor-capacitor) circuit or an RL (resistor-inductor) circuit. The time constant represents the amount of time it takes for a capacitor (for RC circuits) or an inductor (for RL circuits) to charge or discharge 63%.

May 04, 2020 · The time constant of an RL circuit is defined as the time taken by the current to reach its maximum value that had maintained during its initial rate of rise. Considering this, how do you find the time constant of an RL circuit? This time constant τ, is measured by τ = L/R, in seconds, where R is the value of the resistor in ohms and L is the ...

Thus, the time constant for RL circuit may be defined as the: The time it takes the instantaneous current to reach 63.2 percent of its final value. As mentioned earlier current rises exponentially but never reaches the final value until t=∞. We must, therefore, consider some time after which, a constant current flows.
