Measuring time constant rc in a wave

Webthe transient response of the circuit. The pulse-width relative to the circuit’s time constant determines how it is affected by the RL circuit. Time Constant (t): It is a measure of time required for certain changes in voltages and currents in RC and RL circuits. Generally, when the elapsed time exceeds five time WebWe also know that the phase shift of the circuit lags behind that of the input signal due to the time required to charge and then discharge the capacitor as the sine wave changes. This combination of R and C produces a charging and discharging effect on the capacitor known as its Time Constant ( τ ) of the circuit as seen in the RC Circuit ...
