Basic Principles of Wireless Radio Communication - Let us now discuss the basic principles of wireless radio communications. We shall mainly concentrate on the principle of amplitude modulation and demodulation. The simplest scheme of wireless commu..

A positively charged particle can be accelerated to high energy with the help of an oscillating electric field, by making it cross the same electric field time and again with the use of a strong magnetic fiel..

The water flowing in a river is collected by constructing a high rise dam. This stored water is then allowed to fall from the top of the reservoir on to a water turbine located at the bottom of the dam. The fast moving water rotates the blades of the water turbine, which in turn rotates the armat..

Organic chemistry is that branch of chemistry which deals with the study of compounds of carbon with hydrogen (hydrocarbons), and their derivatives. Presently about five million organic compounds are know..

If a system consists of two point charges q 1 and q 2 , then the total charge of the system is got by adding q 1 and q 2 . Thus, the charge add up like real numbers (scalars). When we add charges, one should take care of its sig..

When the blowing wind strikes across the blades of a windmill, it exerts a force on them due to which the blades of the windmill start rotating. This in turn rotates the shaft of the turbine and generates electricity. ..

Introduction - Appliances used in our day to day life are based on the principles of electricity and magnetism. Electricity is one of the most important sources of energy. Lights, fans, motors, radios and television are some common appliances which work on electri..

Electric Motor - An electric motor is a device which converts electrical energy into mechanical energy. It works on the principle that when an electric current is passed through a conductor placed normally in a magnetic field a force acts on the con..

Electricity and Matter - It is important to know the atomic picture of matter. The basic unit of all matter is an 'atom'. Each atom consists of a small core called nucleus which accounts to most of its mass consisting of positively charged protons and neutral neutrons and surrou..
