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 ...

An electric circuit or simply circuit is an arrangement of circuit components such as energy sources, resistors, inductors, capacitors, etc. which allows the flow of electric current from source to load. Based on the ON & OFF condition of the circuit, it can be of two types viz − Open Circuit Closed Circuit In this article, we will discuss the key differences between open and closed circuits. But, before discussing the difference, let's get a basic overview of what open and closed circuits are, which will help in understanding their differences better. What is an Open Circuit? When ...

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 ...

A circuit breaker is a device which makes or breaks the circuit for normal switching and in case of any fault in the circuit. Based on the application, a number of circuit breakers are designed such as MCB, RCCB, MCCB, ELCB, ACB, OCB, etc.In this article, we will discuss the major differences between MCB and MCCB by considering various parameters such as basic definition, tripping circuit, poles, rating, applications, etc. We also added a short description of MCB and MCCB for your reference. What is an MCB? MCB stands for Miniature Circuit Breaker. It is an electromechanical switch which can ... Read More
A printer is an output device that is used to produce a hard copy (i.e. result on a paper) of output produced by any electronic system such as computer, POS-terminal, ATM machine, etc. The printer is hardware device. It can print any type of document like text document, image, or combination of two. It receives input data from the processing system and prints it on a paper. The printers are most common peripheral devices used with computer systems. Based on the technology used in printing, printers can be grouped into the following two categories − Laser Printer Inkjet Printer ... Read More
A transformer is an electrical machine which changes the level of voltage or current to a desired value. A transformer consists of two windings namely, primary winding and secondary winding. These windings are wound on a core and are insulated from the core as well as from each other. When an alternating power supply is connected to the primary winding, it sets up a time varying magnetic field in the core. This changing magnetic field links with the secondary winding to produce an EMF in it which creates a potential difference across the load terminals. Depending on the application, there ... Read More
