It is mainly designed to automate and speed up the process of washing cloths to make life more convenient and efficient. Depending on design and working, different types of washing ... Read More

In electrical and electronics, battery is a device used to store and supply electrical energy. A battery coverts chemical energy into electrical energy. Batteries are one the crucial components in several devices like mobile, laptop, cars, bikes, inverters, UPS, and more. Different types of batteries are used in different applications ... Read More

A furnace is an equipment used to produce heat for a specific purpose. Hence, it is also called heating furnace, as its main function is to generate heat. The heating furnaces are used in various applications such as heat treatment, melting and smelting, ceramic industries, glass production, and many other ... Read More

In electric circuits, there is a device used to detect faulty conditions and protect the circuit from damages. It is known as relay. Thus, a relay can be defined as a device that identify faults and isolate the unhealth section of the circuit from the heathy system. In an electric ... Read More

ConvolutionConvolution is a mathematical tool for combining two signals to produce a third signal. In other words, the convolution can be defined as a mathematical operation that is used to express the relation between input and output an LTI system.Consider two signals $\mathit{x_{\mathrm{1}}\left( t\right )}$ and $\mathit{x_{\mathrm{2}}\left( t\right )}$. Then, ... Read More

In electrical engineering, the power factor of an AC system is the expression of energy efficiency. The power factor (PF) is defined as the ratio of active power (measured in Watts) to the apparent power (measured in VA). The power factor expresses the ratio of true power which is used ...
