Metals are good conductors of electricity because they have:
Correct answer: C. A large number of free electrons
- A. A large number of bounded electrons
- B. Small number of electrons
- C. A large number of free electrons
- D. A small number of free electrons
Explanation
Metals are good conductors of electricity because they have a large number of free electrons. These electrons are not bound to specific atoms but are instead able to move freely throughout the metal lattice. When an electric field is applied, these free electrons can easily flow, creating an electric current.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
