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 considering various parameters. Let's start with a basic overview of MASER and LASER. What is MASER? MASER stands for Microwave Amplification by Stimulated Emission of Radiation. The MASER is a device that emits coherent electromagnetic waves through amplification by the stimulated emission of radiation. The first MASER was invented 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 differences between indicating instruments and recording instruments. Let's start with a basic overview of these two types of instruments. What is an Indicating Instrument? The measuring instruments which indicate the magnitude of the electrical quantity at the time when the quantity is being measured are known as indicating instruments. A ... Read More

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. Hence, in order to reduce the power loss during the transmission, we need to take some necessary actions. One major of them is to increase the transmission voltage to higher values. The line voltage plays an important role in reducing the losses in transmission line. The increase in the line ... 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 system. These chemical processes can produce electricity. The system in which chemical energy is converted into electricity and vice-versa is called a cell. The cells are classified into two major types namely − Electrochemical cell Electrolytic cell In this article, we will highlight how electrolytic cells are different ... Read More

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 are used to carry the electric current, however there are several differences between them. This article will help you understand the major differences between an electrolyte and a conductor. What is an Electrolyte? An electrolyte is a substance whose aqueous solutions are the conductors of electricity. In simple words, a ... Read More

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. There are several circuit breakers are designed for this purpose, two of them are ELCB and RCCB. In this article, you will learn what ELCB and RCCB are, and what are the major differences between them. What is an ELCB? ELCB stands for Earth Leakage Circuit Breaker. The ELCB ... 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 type wattmeter The primary function of both dynamometer and induction type wattmeter is the same, i.e. measurement of active power in the circuit. However, these two types of wattmeters are different from each other in many aspects. In this article, you will learn all the differences between dynamometer ... Read More

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 its plates get polarized, i.e. its charges or ions get separated. The negative ions accumulated near the positive plate and positive ions accumulated near the negative plate. In this way an electric field is established inside capacitor. Hence the capacitor is said to be charged. There are several capacitors available. ... 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, before discussing the difference, we should get the basics of anode and cathode so that the understanding of differences between them becomes easier. What is Anode? An electrode of a device such as cell, battery, diode, etc. where oxidation reaction (loss of electrons) occurs is known as anode. In simple ... 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 of what Alternators and Generators are. What is an Alternator? An electromechanical energy conversion device which converts mechanical energy into AC (alternating current) electrical energy is called an alternator. An alternator consists of two main parts namely stator and rotor. The stator carries the armature winding whereas the rotor carriers ... Read More
