Compact fluorescent lamp (CFL)

Low energy efficiency of incandescent lamps has made them to be replaced with some others energy efficient alternative. Compact fluorescent lamp is one such alternative which can replace almost any incandescent lamp. CFL consist of two parts:

Energy conservation in electrical motors

Energy costs continues to increase due to ever increasing global demand for energy. Industrial sector is awakening in order to reduce cost of production after the markets has the been opened up in early nineties. Decreased production

What is energy conservation

Energy conservation simply means to reduce the growth of energy consumption by avoiding unnecessary usage of energy. Conserving energy helps the planet and saves money—so why don’t more people make the effort to do it? Maybe they

Types of starters

Various types of starters are as follows: Stator resistance starter. Star delta starter. Autotransformer starting. Rotor resistance starters. Variable stator frequency starting. Stator resistance starter A starter resistance is connected in each line series with each phase

Comparison of Induction motor and DC motors

Parameter DC motors Induction motors Supply DC AC Maintenance Frequent Less frequent Speed Low High Size and weight Large Small Speed control Rheostatic control, field control Stator voltage control, stator frequency control. Applications Lathe machine,drilling and milling

Parts of induction motor

A table showing the different parts of motor, the material used for the parts and function of the parts : Parts Material Function Stator frame Case iron Supports the core,protects inner-parts. Stator core Silicon steel Houses stator

Wind tree

Wind Tree, as we can guess from the name, is a wind turbine that looks like a tree. But, that is just a speck of this unconventional wind turbine’s definition. Noisy, Monstrous, Nauseous, giant, unpleasant, bird scaring

Principal of CRT (Cathode ray tube)

Principal of CRT : It consists of an electron gun. The electron gun produce an electron beam. The beam is narrow and is allowed to pass down the tube, and to fall on the screen. The screen

Advantages and disadvantages of digital multimeter

Following are the advantages of digital multimeter : They are having high input impendence, So there is no loading effect. They are having higher accuracy. An unambiguous reading is obtained. The output can be interfaced with external

Ohmmeter

The meter which measures the resistance and the continuity of the electrical circuit and their components such type of meter is known as the ohmmeter. It measures the resistance in ohms. The range of a megger may extend to more
