MCQ
No bias is applied to a $P-N$ junction, then the current
  • A
    Is zero because the number of charge carriers flowing on both sides is same
  • Is zero because the charge carriers do not move
  • C
    Is non-zero
  • D
    None of these

Answer

Correct option: B.
Is zero because the charge carriers do not move
b
(b)In unbiased condition of $PN$-junction, depletion region is generated which stops the movement of charge carriers.
