JEE MAIN - Physics (2004 - No. 11)
When $$p$$-$$n$$ junction diode is forward biased then
both the depletion region and barrier height are reduced
the depletion region is widened and barrier height is reduced
the depletion region is reduced and barrier height is increased
both the depletion region and barrier height are increased
Uitleg
Both the depletion region and barrier height is reduced.
