A transformer is based on the principle of mutual inductio..

The principle behind this technique is the differential adsorption of the various components of a mixture between two different phases that are as follow..

These elements are estimated by its combustion in an atmosphere of pure oxygen to form carbon dioxide (CO 2 ) and water (H 2 O). ..

The generator is an application of electromagnetic induction. It works on the principle that when a wire is moved in a magnetic field, then the current is induced in the coil. A rectangular coil is made to rotate rapidly in the magnetic field between the poles of a horse shoe type magnet...

It is based on the following principles: 1) Action of sharp points: Charges are leaked from pointed ends of charged conductors. This creates an electric wind (as moving air is ionized) which moves away from the conductor. 2) The property that the charge given to a hollow conductor is tra..
