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 ... Read More

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 ... 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 ... 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 ... 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 fluid used such as steam turbine, water turbine, gas turbines, etc. Also, based on the action of fluid (water) the hydro-turbines ...
