MHT CET Physics question

Not in JEE Advanced syllabus

In a p-n junction, there is no appreciable current if

(A)p-section is made positive and n-section negative
(B)A potential difference is applied across junction making p-section negative and n-section positiveCorrect
(C)A potential difference is applied across the junction
(D)Potential barrier is created at junction

Answer: (B)

Solution

Making the p-section negative and the n-section positive is reverse bias, so only a negligible leakage current flows; (a)
