Frictional electricity & Electrostatic induction - Physics Class 12

Frictional electricity-

 

When two different objects (such as a glass rod and Silk) are rubbed together they get electrified. It happens due to transfer of electrons from one object to another object due to the difference in their electro negativities. The object that gains electrons becomes negatively charged while the object that loses electrons becomes positively charged.
