INDUCTOR / COIL

In this video session, we will be discussing about electronic component called an inductor. An Inductor is also known as a coil or choke. It is a passive component with two terminals. There is a loop of copper wire in the inductor, which is fixed on a non-magnetic material. When the current is passed through the inductor, it converts the electric energy into the magnetic field and stores it. There are many types of inductors like air core inductor, iron core inductor, toroid inductor and coupled inductor used in electrical and electronic devices. To become a hardware repairing expert, knowing the features of this component, and its testing procedures are very important. In this session we will learn what is an inductor, how does it look like, the architecture of different inductors, the marking of the inductor on PCB and circuit, the work of inductor, how to Identify bad inductor, and testing procedure of an inductor using a multi-meter.
