In this video session, we will be discussing about electronic component called a capacitor. The capacitor is a passive type electronic component that stores energy in electrostatic form. The capacitor is an electronic component that is designed to add capacitance to the circuit. There are many types of capacitors that are used in electronic development. 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 a capacitor, how does it look like, it’s architecture and types, the marking of a capacitor on PCB and circuit, what is the work of Capacitor in DC circuits, how to Identify bad capacitor, and how can we test a capacitor using a multi-meter.
