Question

In equilibrium state, the rate of generation ________ the rate of recombination of electrons and holes.

Take temperature, $T>0\text{K}$.

• A. is equal to
• B. is greater than
• C. is less than
• D. None of these

Answer 1

The correct option is A is equal to

Apart from the process of the generation of free electrons and holes, a process of recombination takes place simultaneously.

In this process, the electrons recombine with the holes.

In the state of equilibrium, the rate of generation is equal to the rate of recombination.

Hence, option $\left(A\right)$ is the correct answer.
