Question

Why is the base current in a transistor so much less than the collector current?

Answer 1

Answer:

Explanation:

Base is much narrower and thinner than collectors,hence the majority of charge carriers are received by collector.Hence,collector current is greater than base current.

Answer 2

Answer:

Collectors acquire the majority of charge carriers since the base is significantly narrower and thinner than collectors and is weakly doped.

Explanation:

Since the base is narrow and weakly doped, there are fewer majority carriers present. When the bulk of carriers move from the emitter to the collector, the recombination rate of free electrons and holes in the base area is reduced.

The collector's job is to gather all of the moving charge carriers. Heat is dissipated from the charge carriers during the collection operation. The collector has a wide surface area to remove heat, making it larger than the base and emitter.
