A circuit breaker is an electrical switching device that can open or close an electric circuit either normally or in case of fault. Therefore, a circuit breaker is one of the major component of an electrical power system or wiring system. A circuit breaker is usually equipped with a control mechanism which enable it to operate automatically in case of abnormal conditions in the circuit. Since the different electrical systems operate at different voltage and current levels. Therefore, according to system voltage and current, there are various types of circuit breakers available such as MCB (Miniature Circuit Breaker), ACB (Air ... Read More

In electrical machines and instruments, an excitation system is the one which receives electrical energy to produce the working magnetic flux. The excitation system is the crucial component every electromechanical energy conversion device such as electric motor. Depending upon the number of input supplies, any electromechanical energy conversion system can be grouped into the following two categories − Singly Excited System Doubly Excited System In this article, we will discuss the major differences between singly excited system and doubly excited system. Let's start with a basic overview of what singly and doubly excited systems are. What is a ... Read More

Both turbocharger and supercharger are used to increase the pressure of atmospheric air before sending it to the engine cylinder. The compressed air increases the amount of fuel to enter into the engine cylinder for combustion, which in turn increases the power of the engine.Basically both turbocharger and supercharger perform the same operation. However, they are different from each other in many ways, which we are going to highlight in this article. What is a Turbocharger? A forced induction system which uses energy of exhaust gases to compress the atmospheric air and sends it to the engine cylinder is known ... Read More

Sensors and transducers are extensively used in the electrical and electronic instruments to measure different physical quantities. However, there are many differences between a sensor and a transducer that we will discuss in this article. But, before getting into the differences, let's get an overview of what sensors and transducers are, so that it becomes easier to understand how they differ from each other.What is a Sensor? A sensor is a device that detects any physical quantity such as pressure, light, heat, temperature, humidity, etc. from the outside environment and responds according to the input to produce a desired output ...

A cell is an active circuit component that supplies electrical energy to the circuit. A cell stores the energy in the form of chemical energy and converts it into electrical energy when the load is connected across its terminals. Depending on the ability to recharge, the cells are classified into the following two types, viz. − Primary cell Secondary cell Read through this article to find out more about primary cells and secondary cells and how these two types of cells are different from each other. What is a Primary Cell? The type of electric cell which produces electrical ... Read More

A turbine is a device which converts the energy of some fluid into rotational mechanical energy. There are a number of turbines available based on the type of input used such as steam turbine, water turbine, gas turbines, etc.The most commonly used water turbines are Pelton wheel, Francis turbine and Kaplan turbine. Go through this article to find out the major differences between Pelton wheel and Francis turbine. What is Pelton Wheel? A Pelton wheel is an impulse type water turbine in which the entire pressure of water is converted into kinetic energy in a nozzle and the velocity of ... Read More

A type of internal combustion engine which converts the energy of natural gas or other fuel gas into mechanical rotational energy is called a gas turbine. In simple words, a gas turbine is a type of turbine that driven by expanding hot gases produced by the combustion of fuel gas. The gas turbines are broadly classified into two types, viz − Open cycle gas turbine Closed cycle gas turbine This article provides a comprehensive understanding of differences between open cycle gas turbine and closed cycle gas turbine by considering various parameters such as basic definition, working fluid, heat ...

There are many quantities in an electrical and electronic circuit that need to be measured. For this purpose, many types of measuring instruments have been developed such as moving iron instruments, moving coil instruments, dynamometer type instruments, etc. In this article, we will learn about the key differences between moving iron and moving coil instruments by considering various parameters such as basic definition, symbol, uses, scale, working principle, power consumption, etc. But, before discussing about the differences, it is advantageous to know about these instruments in short. What is a Moving Coil Instrument? A type of measuring instrument in which ... Read More

There are two important processes used in data communication namely, modulation and demodulation. Both these processes make a communication successful by the transfer of data and information with the minimum distortion, minimum losses and efficient use of spectrum. The electronic device that is employed to perform modulation and demodulation is called modem. It performs modulation and demodulation of information during its transmission. In this article, we will discuss the major differences between modulation and demodulation by considering various factors such as basic definition, purpose, implementation, need, etc. But before going into the differentiation part, it is beneficial to gather basic ...
