WebQuestion: A certain impedance has a voltage V = 5 cos (100t+30 ) v across it and a current i = 20 sin (100t +60) A through it. What type of load do we have? Does the current lead or lag the voltage? Select one: A resistive load and the current is in phase with the voltage An inductive load and the current lags the voltage. WebLagging current can be formally defined as “an alternating current that reaches its maximum value up to 90° behind the voltage that produces it”. [7] This means that current lags the voltage when is less than . This can also be stated as the voltage and current being out of phase. For an inductor, current lags the voltage.
