Question

A good conductor of electricity is :

• A. hydrogen
• B. oxygen
• C. silver
• D. plastic

Answer 1

The correct option is C

silver

1. Materials that permit electricity or heat to pass through them are called conductors.
2. Electrons move freely within the conductor.
3. The electric field exists on the surface but remains zero on the inside.
4. A few examples of a conductor are silver, aluminum, and iron.
5. Silver is the best conductor of electricity.
6. Materials that do not permit heat and electricity to pass through them are called insulators.
7. Electrons do not move freely within the insulator.
8. The electric field doesn’t exist.
9. A few examples of an insulator are paper, wood, and rubber.

Hence, the correct option is an option (C).
