In figure given below V 0 is the potential barrier across a p − n junction, when no battary is connected across the junction

Question

In figure given below V 0 ​ is the potential barrier across a p − n junction, when no battary is connected across the junction, 1 and 3 both correspond to forward bias of junction, 3 corresponds to forward bias of junction and 1 corresponds to reverse bias of junctions, 1 corresponds to forward bias and 3 corresponds to reverse bias of junction, 3 and 1 both correspond to reverse bias of junction

MARKS App · Accepted Answer

When p-n junction is forward biased then the depleton layer is compresses or decrease so it opposes the potential junction resulting decrease in potential barrier junction when p-n junction is reverese biased, it supports the potential barrier junction, resulting increase in potential across the junction.
