Analog & Digital Multimeter

Analog & Digital Multimeter

A basic multimeter can measure the three basic electric values (i.e., voltage, current, and resistance), but more functions can also be included in a multimeter. Initially, there are two types of multimeters, analog and digital. A multimeter is a must-have tool for someone working with electricity and electronics. It is …

What is Capacitance | Definition & Formula

What is Capacitance

Definition: Capacitance is a property that opposes any change in voltage. A capacitor is a device that temporarily stores an electric charge. A capacitor accepts or returns this charge in order to maintain a constant voltage. Schematic symbols that are used to represent a capacitor are shown in Figure 1. …
