According to the electron theory of matter, we know that all matter (solid, liquid, or gas) is made of tiny particles called molecules. A molecule in turn is made up of atoms. Thus, atoms are the basic building blocks of all matter. An atom consists of a central part called ... Read More

What is Electric Charge? The physical property of a substance that causes charged substance to experience a force when placed in an electromagnetic field is called electric charge. In other words, electric charge is the physical property of the subatomic particles of matter due to which matter shows electrical behavior. ... Read More

The slow movement of something toward an object is termed as drift. The average velocity of electrically charged particles in a material under the influence of an electric field is called the drift velocity. In this article, we will learn in detail about drift velocity, carrier mobility, and drift current. ... Read More

In this article, we shall discuss electrical conductance and conductivity, its definition, formula, unit of measurement, and the solved numerical examples. What is Electrical Conductance? The measure of how easily the electric charge (or electrons or electric current) can flow through a material is called the conductance or electrical conductance ... Read More

The branch of engineering that deals with the study of design and implementation of various electrical devices and systems used in our everyday life as well as generation, transmission and distribution of electrical power is popularly known as Electrical Engineering. Electrical engineering primarily convers the study of electric circuits, power ... Read More

The energy of flowing wind is a versatile source of renewable and sustainable energy. In practice, people use the terms Windmill and Wind Turbine interchangeably, but these two terms are different from each other. Windmill and wind turbines are different from each other in structure and application. Windmill is ... Read More

In atomic structure, valance band and conduction band are the terms used to represent the energy levels of the subatomic particles, usually electrons. While analyzing the atomic structures, we found that the valance band and conduction band are separated by a certain amount of energy depending on the type of ... Read More

In electrical and electronics engineering, transformers and amplifiers play a crucial role in several circuits. At first sight, the function of a transformer and an amplifier may seem similar, that is, increasing the level of voltage. But, a transformer can reduce the level of voltage as well, whereas an amplifier ... Read More

A rotating electric machine is the one which has moving parts. Every rotating electrical machine such as motor and generator consists of two major parts namely stator and rotor. As their name implies, the stator is that part of the machine which is stationary or non-movable, whereas the rotor is ... Read More

In electrical and electronics engineering, a Relay is an electrically operated switch which is used to connect or disconnect two circuits. Since the operation of a Relay is governed by an electric control signal, hence it can be operated automatically. Basically, the relays are designed for switching of high power ... Read More
