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. Sometimes a length of wire, or a pair of wires, is used as an inductor. What is Inductance? Suppose you have a wire 1 million … [Read more...] about Inductors and Inductance : Working, Unit, Function, Types and Uses
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 not available, then insulate yourself by standing on a dry wooden board, thick … [Read more...] about How to Rescue a Person from Electric Shock?
In this article, you will study what are electric potential, the potential difference (PD) and electromotive force (emf) and the difference between them. Just as a body raised above the ground has gravitational potential energy, similarly, a charged body has electric potential energy. When a body is charged, work is done in charging the body. This work done is stored in the … [Read more...] about Electric Potential, Potential Difference and EMF
Basically, a capacitor is formed from two conducting plates separated by a thin insulating layer. There are different types of capacitors that are manufactured in many forms, styles, and materials. Understanding the basics of them helps you to choose the capacitor for your application. Before going to each of them, let us understand the basic uses of a capacitor in a circuit. … [Read more...] about Different Types of Capacitors and their Uses
The Stroboscopic Effect in Fluorescent lamp is a phenomenon which causes running or moving equipment to appear stationary or appear to be operating slower than they actually are. Fluorescent materials when subjected to electromagnetic radiations of a particular wavelength, get excited and in turn, gives out radiations at some other wavelength. This is the working … [Read more...] about Stroboscopic Effect in Fluorescent Lamps
