Question

Which operating region of BJT enables Emitter-base & Collector-base junctions to undergo perfect short-circuit configuration ?

• A. Active Region
• B. Saturation Region
• C. Cut-off Region
• D. None of the above

Answer 1

Answer: (B)

Saturation Region

BJT is a transistor.

Forward bias is a condition in which the p-side is connected to the positive terminal of the power supply, and n-side to negative.

In this condition, the device becomes a very good conductor.

In the saturation region, both junctions of the BJT get forward biased and the whole transistor becomes a good conductor.

This condition is similar to the positive and negative of power supply coming under direct contact. It acts like a short circuit condition.
