What happens to the total charge of a system of two blocks before and after a charging process?

Back

The total charge remains the same before and after the charging process.

Front

Can electrons move between two blocks if they are not in contact?

Back

No, electrons cannot move between the blocks without touching.

Front

When an object gains electrons, what charge does it acquire?

Back

Coulomb (C).

Front

What is the principle of conservation of charge?

Back

The total electric charge in an isolated system remains constant.

Front

What is the difference between conductors and insulators?

Back

Conductors allow the flow of electric charge, while insulators do not.

Front

What is static electricity?

Back

Electric charge at rest, typically produced by friction.
