Front

What is charging by conduction?

Back

Charging an object by direct contact with another charged object.

Front

What is the role of insulators in static electricity?

Back

Insulators prevent the flow of electric charge, allowing static charges to build up.

Front

What is the principle of conservation of charge?

Back

Charge can neither be created nor destroyed; it can only be transferred.
