In case of NPN-transistor the collector ...

In case of `NPN`-transistor the collector current is always less than the emitter current because

A

collector side is reverse biased and the emitter side is forward biased

B

a few electrons are lost in the base and only remaining ones reach the collector

C

collector being reverse biased, attracts less electrons

D

collector side is forward biased and emitter side is reverse biased

Text Solution

Verified by Experts

The correct Answer is:
B
In a transistor, the collector current is less than the emitter current because a few electrons are lost in the base and only remaining ones reach the collector.
