Vedclass · Answer

(A) The depletion layer is formed at the $PN$ junction due to the diffusion of electrons and holes across the junction. This process leaves behind immobile positive ions on the $n$-side and immobile negative ions on the $p$-side. Because these ions are fixed in the crystal lattice and cannot move,the depletion layer is effectively devoid of free charge carriers. Since electrical conductivity depends on the presence of mobile charge carriers,the absence of these carriers results in a very high electrical resistance in the depletion layer.

The electrical resistance of the depletion layer is large because
