Question

In case of npn transistors, the collector current is always less than the emitter current because ______.

पर्याय

• collector side is reverse biased and emitter side is forward biased.

• after electrons are lost in the base, only remaining ones reach the collector.

• collector side is forward biased and emitter side is reverse biased.

• collector being reverse biased attracts less electrons.

Answer 1

In case of npn transistors, the collector current is always less than the emitter current because after electrons are lost in the base, only remaining ones reach the collector.

Explanation:

`"I"_"E" = "I"_"B" + "I"_"C" => "I"_"C" = "I"_"E" -  "I"_"B"`
