Why current lags voltage in inductors (logic) - Khan Academy

WebMay 30, 2024 · Current and voltage start from the same physical phenomenon, electromagnetism, but they are totally different effects. In the inductance, being a coil, a magnetic field is generated by circulating a current through it. This current is maintained if the voltage to the coil is suddenly stopped. Webvoltage, current and power for a purely inductive load Current lags the voltage by 90 degrees. Instantaneous power has an average of zero. Energy flows from source to the load half of the time and from the load back to the source the other half of the time. Apparent power is 0.5 VA. Real power is zero. Reactive power is 0.5 Volt-Amperes ...
