Question

Which particles are responsible for current in conductors?

Answer 1

1. Conductor is defined as substances or materials that allow electricity to flow through them easily.
2. Most of the metals are the good conductor of electricity.$e.g$ silver, aluminum, copper, gold.
3. Metals atoms have loose electrons in the outer shells, which form free negative charge around the close-packed positive ions.
4. Loose electrons are called free electrons.
5. They can move freely in the metal structure.
6. Electric current is the flow of these free electrons in one direction.

Hence, particles are responsible for current in conductors are Free electrons.
