Inductors are electrical components that oppose the flow of alternating current (AC) by temporarily storing energy as magnetic fields. The action of an inductor is known as Inductance. Inductors often, but not always, consist of wire coils. … Continue Reading about Inductors and Inductance : Working, Unit, Function, Types and Uses

How to Rescue a Person from Electric Shock?
If a person receives an electric shock, it is the utmost duty of the observer to rescue the person. The first step is to disconnect the person immediately from the live supply mains by either switching off the main switch. The body should be pushed away with a dry stick or rope. If a stick is … Continue Reading about How to Rescue a Person from Electric Shock?
