What are di-electrics????
What is polarisation????
What is the principle of van de graaff generator????
Can you plz. tell me the imp. topics which i should prepare 4 my exams in this chapter????
A 'dielectric' is a nonconducting substance, i.e. an insulator
Commercially manufactured capacitors typically use a solid dielectric material with high permittivity as the intervening medium between the stored positive and negative charges. This material is often referred to in technical contexts as the "capacitor dielectric"
van de graff generator:
A Van de Graaff generator is an electrostatic machine which uses a moving belt to accumulate very high electrostatically stable voltages on a hollow metal globe
