MASER and LASER technologies are based on the concept of stimulated emission of radiation. In the process of stimulated emission, an electron goes to a lower energy level due to an interaction with the electromagnetic waves. In this article, we will highlight the key differences between MASER and LASER by ... Read More

A device that is used for indicating and measuring various electrical quantities like current, voltage, energy, power, etc. is called a measuring instrument. Based on the functionality, the instruments can be classified in several types like indicating instruments, integrating instruments, recording instruments, etc.In this article, we will highlight all the ...

Electrical power is produced at the generating plants, from where it is transmitted over the long distances for utilization at the load points. Since, the transmission of electrical power is performed with the help of transmission conductor. Hence, due to the line parameter, some power loss occurs during the transmission. ... Read More

A cell is a device that converts chemical energy into electrical energy and vice-versa. The behavior of the cells is studied in a branch of chemistry called electrochemistry, where we learn about the relation between the movement of electrons in a system and the chemical processes take place in the ...

It is a well-known fact that the electric current is the flow of charges. This charge may be carried by electrons or ions. Hence based on the charge carriers and physical state, there are two types of substances used for current conduction namely electrolytes and conductors. Both electrolytes and conductors ...

A circuit breaker is an electrical switch that is designed to operated manually as well as automatically either in normal conditions or in case of a fault in the system. Therefore, a circuit breaker can also function as a protective device which can protect the system equipment and the operators. ... Read More

A wattmeter is an electrical measuring instrument that measures active (or real) power in an electric circuit. It measures the value of electric power in watts, kW, MW, etc. Based on the principle and construction, the wattmeters are classified into two major types as − Dynamometer type wattmeter Induction ...

A capacitor is a circuit component which has ability to store electrical energy in the form of electrostatic field. A capacitor consists of an assembly of two parallel plates that are separated by an insulating material called dielectric. When a voltage is applied to the capacitor, the dielectric material between ... Read More

Any electric circuit element or device has terminals for making connection in the circuit. These terminals of the element are also called electrodes of the element. The electrodes are classified in two types namely anode and cathode. This article is meant for explaining the difference between anode and cathode. But, ... Read More

Both alternator and generator are types of electromechanical energy conversion devices that convert mechanical energy into electrical energy, however there are several differences in the way they operate. This article will help you understand the major differences between an alternator and a generator. Let's start with a basic overview ... Read More
