DC motor runs on direct or dc current. On this page we shall understand the function of each component of the motor. In general there are two major parts of any motor i.e. stationary part and moving part. The stationary part is mainly the outer part that houses the field windings and receives the supply also… Read More »
The speed of a dc shunt motor is directly proportional to the back emf and inversely proportional to the flux per pole. DC shunt motors are very useful and important part of any motor application. The motor speed control in dc shunt motor is very crucial because it impacts the use and design of the… Read More »
Fiber Optic cable is made up of thin fibers which are useful for the transmission of large amount of data. Infact the optical fiber is a hair thin cylindrical fiber of glass or any transparent dielectric medium. The fiber which are used for optical communication are wave guides made of transparent dielectrics. Its function is… Read More »
Solar cell is a device or a structure that converts the solar energy i.e. the energy obtained from the sun, directly into the electrical energy. The basic principle behind the function of solar cell is based on photovoltaic effect. Solar cell is also termed as photo galvanic cell. The electricity supplied by the solar cell is… Read More »
This page explains how solar panels work, actually we shall understand what is photovoltaic effect that causes the light to convert in to the electricity or energy. In fact photovoltaic effect also called photoelectric effect is the effect that causes the production of solar electricity using the specific semiconductor materials. Before looking in depth the process of solar energy… Read More »
In new era, alkaline battery is one of the most important and most useful equipment. Normally battery is used where power supply is not regular and where low voltage is required (i.e. lower than supply voltage). Watches, mobiles and many other small equipment’s that require lesser voltage, mainly run on battery. The main advantage of battery is, they can be charged… Read More »
