Question

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.

Answer 1

The answer is option C

Answer 2

Dear Student,

◆ Answer - (C)

When a forward bias is applied to a p-n junction, it lowers the potential barrier.

● Explanation -

• It consists of p-type semiconductor joined with n-type semiconductor.
• In forward bias, p-type semiconductor is connected with positive terminal and n-type semiconductor is connected with negative terminal.
• Here, negative voltage pushes electrons across the barrier which reduces potential carrier.

Thanks dear...
