Types of Charging Process:

⇒ Charging by Friction

• After rubbing the balloon against the hair, the electrons from hair are transferred to the balloon, hence, the balloon becomes negatively charged and the hair becomes positively charged.

⇒ Charged by Induction

• When a negatively charged balloon brought near a can, the electrons in the can move away from the balloon, leaving the other side of the can positively charged hence, attraction between the objects occurs.

⇒ Charged by Conduction

• When a negatively charged balloon brought near a can, the electrons are pushed to the far side of the can. When another object - the finger - touches the side of the can opposite the balloon ,electrons flow into the finger, leaving the can positively charged.

Guide Questions:

1. When two objects are rubbed against each other, what charge has been transferred?

• When two materials are rubbed against each other, there is a transfer of electrons from one material to the other material.

2. What charging process occurs when a charged body brought in contact to a neutral body?

• Charging by conduction
