In a p-n junction in an unbiased condition

Answer»

the POTENTIAL is the same everywhere.
the p-side is at a higher potential than then-side.
an electric field exists at the junction directed from then-type side top-type side.
an electric field exists at the junction directed from the p-type side to n-type side.

Solution :In a p-n junction in its unbiased condition due to DIFFUSION and DRIFT CURRENTS potential of n-side of junction is higher than that of p-side and CONSEQUENTLY an electric field exists at the junction directed from then-side top-side.
