Question # 1

Define electric polarization and electric dipole.

  • Ans 1: When dielectric is placed between the plants of capacitor,positive and negative charge of its molecules displace from their position.Positive charges are attracted towards negative plates and negative charges towards positive plate,dipoles are formed.This process is called polarization.
    Two equal and opposite charges separated by a small distance is called dipole.
