Question:

During the formation of depletion layer around the imaginary pn-junction, electrons diffuse from nregion to p-region because.

Options:

Electron concentration in n-segment is higher than electron concentration in p-segment

Holes of p-segment attract the electrons

Electrons are lighter and have higher drift velocity

Hole concentration in n-segment is higher than the electron concentration in p-segment

Correct Answer:

Electron concentration in n-segment is higher than electron concentration in p-segment

Explanation:

The correct answer is option (1) : Electron concentration in n-segment is higher than electron concentration in p-segment

During the formation of depletion layer around the imaginary pn-junction, electron diffuses from n-region to p-region because electron concentration in n-segment is higher than electron concentration in p-segment
