Question

The value of $\alpha$ (ratio of collector and emitter current):

• A. is always less than $1$
• B. is always greater than $1$
• C. may be less or greater than $1$
• D. none of these

Answer 1

The correct option is A is always less than $1$

In a transistor circuit collector current is always less than emitter current hence ratio of collector current and emitter current is always less than 1.

i.e. $\alpha$ is always less than 1.
