Question

What do a moving student and a vacant seat represent when an electron moves into the conduction band?

विकल्प

• A free electron and a hole created simultaneously.

• Two free electrons created simultaneously.

• An impurity atom and a majority carrier.

• Two holes created simultaneously.

Answer 1

The moving student represents the free electron, and the vacant seat represents the hole. Similarly, moving a valence electron into the conduction band creates both simultaneously.
