Question

The phenomenon known as “Early Effect” in a bipolar transistor refers to a
reduction of the effective base-width caused by
(A) Electron - hole recombination at the base
(B) The reverse biasing of the base - collector junction
(C) The forward biasing of emitter-base junction
(D) The early removal of stored base charge during saturation-to-cut off
switching

Answer 1

Answer:

The correct answer for the question asked at hand is the option titled B,

i.e. The reverse biasing of the base- collector junction

Explanation:

In the case of discussion of Early Effect in a bipolar transistor there happens a reduction because of the reverse biasing of the base- collector junction, and it leads to a reduction in the effective base width.

This can be explained as reverse biasing of the base means the relationship of how there is a negative negative direction which denotes that emitter junction is reverse biased. This causes electron-hole pairs to be generated. And while the electrons flow to the collector it makes the holes not able to flow out of the base contact.

Answer 2

The phenomenon known as “Early Effect” in a bipolar transistor refers to a. reduction of the effective base-width caused by. (A) Electron - hole recombination at the base. (B) The reverse biasing of the base - collector junction.
