Play an AI-generated podcast conversation about this lesson

What does the principle of conservation of charge state?

The total charge before and after an interaction is always different

Charge can be created or destroyed during physical processes

The net charge of an isolated system remains constant during any physical process (correct)

Charge is only transferred from one material to another

What is a characteristic of conductors?

Charge remains concentrated in one area

Electrons are bound tightly to the atoms

They are poor insulators

Electrons can move relatively freely (correct)

What happens to an excess charge placed on a conductor?

The charge is transferred to an insulator

The charge is destroyed

The charge remains concentrated where it was placed
