The Total solution for NCERT class 6-12
When a forward bias is applied to a p-n junction, it
(a) raises the potential barrier.
(b) reduces the majority carrier current to zero.
(c) lowers the potential barrier.
(d) None of the above.
The correct statement is (c).
When a forward bias is applied to a p-n junction, itlowers the value of potential barrier. In the case of a forward bias, thepotential barrier opposes the applied voltage. Hence, the potential barrieracross the junction gets reduced.
