In capacitive circuit current leads or lags
WebOct 9, 2024 · using the above equation one can get the response of the capacitor and inductor to harmonic signals in steady state: Then i= wCVm cos wt = wCVm sin (wt +pi/4) … WebJan 10, 2024 · The phase difference is lesser than equal to 90 degrees. It is usual to use the angle by which the voltage leads the current. This leads to a positive phase for inductive circuits since current lags the voltage in an inductive circuit. The phase is negative for a capacitive circuit since the current leads the voltage.
