Uses of Static Electricity

Static electricity is the type of electricity that is created when their is unbalance of electric charges leading to the transfer of charges from one body to another.

This electricity is formed by friction between two insulating materials. When the materials are rubbed together, electrons are removed from atoms within the materials.

Rubbing the balloon against hair causes electrons to move from the hair to the balloon.

Because electrons are negatively charged, the balloon acquires a negative charge, while the hair, with its loss of negative charges, now has a net positive charge.

Therefore, the charges on the balloon and on his hair changed because the charge on the balloon became negative. the charge on his hair became positive.
