When a p-n junction diode is forward-biased
- (a)it acts as an insulator and no current flows through it.
- (b)it offers a low resistance and a large current flows through it.
- (c)it offers a high resistance and a small current flows through it.
- (d)the width of depletion region increases.

Correct option: (b)
Answer: (b) it offers a low resistance and a large current flows through it.
In forward bias, the applied voltage opposes the barrier potential and reduces the width of the depletion region, so the diode offers low resistance and allows a large current to flow.
