Dielectric:
The word dielectric means nothing but insulator.It means that a dielectric material is something which do not allow the flow of current through it.
Dielectric Strength:
It is defined as the limit of filed strength i.e the property of an insulator that can withstand or oppose the flow of current without breakdown.The breakdown field of an insulator is 10,000 .
That means above this limit of breakdown field the insulator starts conducting the current and behaves as a conducting material.
Inductance:
It is a property of a conductor in which,as the current flowing through it is being changed continuously there will be change in its EMF.The inductance of a material is denoted by letter L and is measured in Henry
These inductance is of two types :
1.Self inductance:
It is the ratio of change of emf of a circuit to the change of current in the same circuit.
2.Mutual inductance:
It is the ratio of change of emf of a circuit to the change of current in a neighbouring circuit.
