Hey thanks for the question

Here is answer

In a intrinsic semicondutor the number of electrons is equal to the number of holes

Keep in note that intrinsic semiconductors are the pure semiconductors

Hope this answered your question ♥

Answer 2

The number of excited electrons and the number of holes are equal.

Explanation:

Semiconductors are the materials whose condctivity lies between conductor and insulators. An intrinsic semiconductor is an undoped semiconductor. In this type of conductor, no dopant species present.

In intrinsic semiconductors, the number of excited electrons and the number of holes are equal i.e.
