What is an Inductive Ballast?Inductive Ballast definitionInductive Ballast is an iron core inductance coil, the nature of inductance is that when the current in the coil changes, it will cause a change in magnetic flux in the coil, resulting in induced electromotive force, and its direction is opposite to the direction of the current change, thus hindering the current change.Working principle of Inductive BallastWhen the 220V 50Hz AC power supply is applied in the switch closing circuit, the cur
