Question

conduction of current in npn transistor due to
a- holes
b- electron
c- both​

Answer 1

Answer:

b-electron

Explanation:

The conduction of current in NPN transistor is owing to electrons and in PNP transistor, it is owing to holes. The direction of current flow will be in opposite direction. ... Thus we can conclude that, the whole emitter current in this transistor is due to the passage of holes from the emitter to the bas
