Question

Which particles constitutes the electric current in a metallic conductor?

Answer 1

Concept used: Electric current

Prerequisite: Knowledge of electric current

1. The metallic conductors have two types of charged particles, positively charged particles, and negatively charged particles.
2. Positively charged particles are protons, and negatively charged particles are electrons in the metallic conductor, the electric current flow due to the presence of electrons.
3. These electrons are situated in the outer shell of the orbit. When a potential difference is applied to the metallic conductor, then these electrons are detached from the outer shell and start moving, and consequently, the current flow in the conductor.

Thus, the electrons constitute the electric current in a metallic conductor.
