Q. When a p-n junction is reverse biased :

A
holes and electrons move towards the junction
B
holes and electrons move away from the junction
C
movement of holes and electrons are seized
D
width of depletion region decreases
Solution:

If the reverse biased voltage applied on the p-n junction diode is further increased, then even more number of free electrons and holes are pulled away from the p-n junction. This increases the width of depletion region. Thus, the minority charge carriers carry the electric current in reverse biased p-n junction diode.
