How many types of flow are there in a semiconductor?

A. 0

B. 1

C. 2

D. 3

E. None of the above

Answer: Option B

Solution (By Examveda Team)

The correct answer is C: 2
Here's why:
In a semiconductor, there are two main types of charge carriers that contribute to current flow:
1. Electrons: These are negatively charged particles.
2. Holes: These are the absence of electrons, effectively acting as positive charge carriers. Think of them as bubbles in a liquid; when a bubble moves, it's the liquid moving around it that creates the bubble's apparent movement.
Therefore, there are two types of flow (electron flow and hole flow) in a semiconductor.
