Question

Early effect in bipolar transistor is caused by

• A. Fast turn on
• B. Fast turn off
• C. Large collector base reverse bias
• D. Large emitter base forward bias

Hint:

The Early effect is related to the modulation of the base width due to changes in the collector-base junction reverse bias.

Answer 1

The Correct Option is C

The Early effect in a bipolar junction transistor (BJT) is caused by a large collector-base reverse bias voltage. An increase in this reverse bias voltage effectively reduces the width of the base region and increases collector current, leading to the Early effect.
