Vedclass · Answer

(A) In a $p-n$ junction diode,the diffusion current is caused by the concentration gradient of charge carriers.Due to the higher concentration of holes in the $p-$ region and electrons in the $n-$ region,holes diffuse from the $p-$ region to the $n-$ region,and electrons diffuse from the $n-$ region to the $p-$ region.By convention,the direction of electric current is the direction of the flow of positive charge (holes).Therefore,the diffusion current flows from the $p-$ region to the $n-$ region.

In a $p-n$ junction diode,the direction of diffusion current is from
