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. This article …
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 …
In recent years, cells and batteries—especially cells—have become available in many different sizes and shapes besides the old cylindrical cells, transistor batteries and lantern batteries. In this article, you will …
The directed flow of free electrons (or charge) is called the electric current. The electric current may be classified into three main types: Steady current (DC Current) Varying current Alternating …
In this article, you’ll learn about electrical components that oppose the flow of AC by temporarily storing energy as electric fields. These devices are called capacitors, and their action is …
The electromagnetism lecture notes is a book to provide an introduction to Electromagnetism for Electrical and Electronics Engineers. These are compiled by David Tong, Department of Applied Mathematics and Theoretical …
This is the complete guide to learn electrical engineering basics in 2020. The study of electrical engineering involves the analysis of the energy transfer from one form to another or …
A ground fault circuit interrupter (GFCI or GFI) is an inexpensive electrical switchgear device that can either be installed in your electrical system or built into a power cord to protect …
This article explains the measurement of three-phase power in star connected or delta connecter load using the wattmeter methods. The power in a three phase load can be measured by …
