1.Charging by Rubbing
Charging by rubbing, also known as charging by friction, is a process of charging an object by rubbing it against another object. This process results in the transfer of electric charges between the two objects.
2.Charging by Friction:
Charging by friction is a process of charging an object by rubbing it against another object, such that electrons are transferred from one object to the other. The object that gains electrons becomes negatively charged, while the object that loses electrons becomes positively charged. Examples of charging by friction include rubbing a glass rod with silk, rubbing a plastic comb with hair, and rubbing a balloon with a woolen cloth.
3.Charging by Induction:
Charging by induction is a process of charging an object by bringing it close to a charged object, without making physical contact. The charged object induces an opposite charge on the surface of the neutral object, which results in the separation of charges. The neutral object becomes charged with a charge opposite to the inducing charge. Examples of charging by induction include bringing a negatively charged rod near a neutral metal sphere and bringing a positively charged balloon near a neutral metal sphere.
3.Charging by Conduction:
Charging by conduction is a process of charging an object by touching it with a charged object. When a charged object is brought in contact with a neutral object, the charges get distributed over the entire surface of the neutral object. If the charged object has a different charge than the neutral object, then the neutral object becomes charged with the same type of charge as the charged object. Examples of charging by conduction include touching a charged rod to a neutral metal sphere and charging a metal object by connecting it to a battery.
