In case of NPN-transistors the collector current is always less than the emitter current because.

A

Collector side is reverse biased and emitter side is forward biased

B

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

C

Collector side is forward biased and emitter side is reverse biased

D

Collector being reverse biased attracts less electrons

Answer

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

Explanation

Solution

ie=ib+ic⇒ic=ie−ibi_{e} = i_{b} + i_{c} \Rightarrow i_{c} = i_{e} - i_{b}
