MCQ
When a forward bias is applied to a $p-n$ junction, it
- ARaises the potential barrier
- BReduce the majority carrier current to zero
- ✓Lower the potential barrier
- DNone of the above
✓
Answer
Correct option: C.
Lower the potential barrier
c
When forward bias is applied to a $p-n$ junction, it lower the values of potential barrier. In the case of forward bias, the potential barrier is opposed by the applied voltage. Hence, the potential barrier across the junction gets reduced.
