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 ...

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 fluid used such as steam turbine, water turbine, gas turbines, etc. Also, based on the action of fluid (water) the hydro-turbines are classified into two types, viz. Impulse Turbine Reaction Turbine In this article, we will discuss all the major differences between an impulse turbine and a reaction turbine. But, before discussing the difference, let's get a basic overview of these two types of turbines. What is an ... Read More

Electronics and Power Electronics are the two branches of electrical and electronics engineering. They seem similar, but there are many differences between them. In this article, we will explain what electronics and power electronics are and the major differences between them. What is Electronics? The term Electronics represents the field of engineering which deals with the study of emission, behavior and control of electrons in vacuum, gases and semiconductors and with the electronic devices such as diode, transistors, etc. Based on the type of signal processing, the electronics is broadly classified into two types viz. analog electronics and digital electronics. ...

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 fluid used such as steam turbine, water turbine, gas turbines, etc.In this article, we will discuss about Francis turbine and Kaplan turbine and the key differences between them. Both Francis turbine and Kaplan turbine are types of water turbines, where the hydraulic energy of water is converted into mechanical energy (rotation of turbine). Basically, both Francis and Kaplan turbines come under the category of reaction turbine, which means in both cases, ... Read More

A synchronous generator, also called alternator, is a most widely used electric generator that produces alternating current supply. It is the main component of every power generating station. Based on the rotor construction, the synchronous generators are of two types namely − Cylindrical Rotor Synchronous Generator Salient Pole Rotor Synchronous Generator However, both types of generators are similar in stator construction. The stator of both types of generators consist of a three-phase winding distributed over its inner periphery. In this article, we will explain the key differences between cylindrical rotor and salient pole rotor synchronous generators along ... Read More

A transformer is a static electrical machine that is used for increasing or decreasing the value of alternating voltage or current. Based on the applications, the transformers are classified into following main types − Power transformer Distribution transformer Instrument transformer The instrument transformers are used for the protection and measurement purposes in the electrical power systems and are further classified into two types viz. current transformer (CT) and potential transformer (PT). In this article, we will explain the differences between current transformer and potential transformer along with their basic description. What is a Current Transformer? A current ... Read More

Both cell and battery are the sources of electrical energy in any electrical circuit that provide necessary excitation to the circuit. The cell and battery always deliver electric power to the circuit in the form of direct current (DC), they can never deliver alternating current (AC). Therefore, in practice, the cell and battery are the primary sources of direct current (DC) electricity. However, the working principle of both cell and battery is the same, i.e. electrochemical reactions where the electrical energy is converted into chemical energy and vice-versa. In this article, we will compare cell and battery by considering ... Read More

Both capacitor and supercapacitor are passive circuit components that store electrical energy in the form of electrostatic charge. Thus, the primary function of capacitor and supercapacitor is the same, i.e., storage of electric charge. However, there are many difference between a capacitor and a supercapacitor.In this article, we will discuss the key differences between capacitor and supercapacitor by considering various parameters such as definition, construction, types, energy density, etc. But before that we should learn the basics of capacitor and supercapacitor so that it becomes easier to understand the differences.What is a Capacitor?A capacitor is a two terminal passive circuit ...

Electrical power is produced at the generating stations which is then transported to the points of utilization with the help of electric power lines. The electric utility companies install two different types of electric power lines viz. transmission line and distribution line for conveying the electric power from power plant to consumer’s premises for utilization.This article is meant for describing the key differences between transmission line and distribution line. We also briefly explained that what the transmission line and distribution line are.What is a Transmission Line?Transmission lines are the power lines that carry the electric power at high voltage from ...
