MCQs on Introduction to Diodes


During diffusion, decrease in energy level of conduction band in n region is due to loss of

lower energy electrons
1st shell electrons
2nd shell electrons
higher energy electrons


If a block of Si is doped with a trivalent impurity atoms and other part with pentavalent impurity, a boundary is formed between n and p type, called

PN junction
pPN junction
pnn junction
pp junction


Barrier potential for Si at 25°C is

0.7 V
0.9 V
1.5 V
3 V


When PN junction is formed, n region loses free electrons as they diffuse across the junction, this create a layer of

positive charges
negative charges
neutron charges
photon charges


Region near PN junction is depleted across junction is called

conduction region
floating region
pn region
depletion region
