An electric battery consists of a number of electrochemical cells, connected either in series or parallel. A cell, which is…

This theory was first advanced by Weber in 1852 and was, later on, further developed by Ewing in 1890. The…

A capacitor essentially consists of two conducting surfaces separated by a layer of an insulating medium called dielectric. The conducting…

An insulator or dielectric is a substance within which there are no mobile electrons necessary for electric conduction. However, when…

Electrostatics is that branch of science which deals with the phenomena associated with electricity at rest. Generally an atom is…

When an alternating potential difference is applied across two conductors whose spacing is large as compared to their diameters, there…

The phenomenon of corona is affected by the physical state of the atmosphere as well as by the conditions of…

Corona has many advantages and disadvantages. In the correct design of a high voltage overhead line, a balance should be…

It has been seen that intense corona effects are observed at a working voltage of 33 KV or above. Therefore,…

For high voltages (>33 KV), it is a usual practice to use suspension type insulators consist of a number of…
