Working of Diode rectifiers (Uncontrolled rectifiers)
Introduction Circuits that are used to convert the Alternating Current (AC) input power into a Direct Current (DC) output power is known as rectifier circuits. Rectifiers are found in almost…
Comparision of conventional energy resources
Conventional energy is obtained from the conventional energy resources such as coal, diesel, gas and nucleus. These are non-renewable resources and may exhaust in few decades if consumed at the current…
How does a LCD work?
Metal halide (MH) lamp
Metal halide (MH) lamp provides high efficiency, long service life and excellent colour rendition. It consists of an arc tube enclosed in a glass chamber made up of borosilicate glass. Arc tube is also called as discharge tube or “burner”. The arc tube consists of argon gas, mercury and metal salts such as sodium iodide. They operate at higher temperatures and pressures.Ballast is used to supply a high starting voltage. The ballast also regulates the lamp starting current and lamp operating current. (more…)
How refrigerators work?
Modern fridges are available in various sizes with different features incorporated by the manufacturers. Apart from these features the basic principle of refrigeration of course remains the same. The method of deployment hasn’t changed much since from the aforementioned Frigidaire unit in 1923.What is inductance?
It is a property of a circuit element called inductor to store energy in the magnetic field when current passes through it. A basic inductor can be made by…
What is voltage?
There are two types of charges namely positive charge and negative charge. As we all know these charges are opposite and they attract . A work is done to separate…
