Question

Conductors conduct electricity due to the presence of large number of-
1. atoms
2. neutrons
3. protons
4. free electrons

Answer 1

Correct Answer - Option 4 : free electrons

The correct answer is option 4) i.e. free electrons

CONCEPT:

• Conductors: ​Atoms of conducting materials have free electrons in them
  • When a potential difference is applied across the ends of a conductor, the electrons drift from the lower potential to the region of higher potential.
  • This movement of electrons constitutes an electric current.

EXPLANATION:

• Conductors conduct electricity due to the presence of a large number of free electrons.
