### Choose the right answer to the question, ‘the value of current gain in CB configuration is always_____’ from the following options:

A. less than 1.
B. Between 1 and 50.
C. Between 100 and 200.
D. Undefined.

## The answer to the question, the value of current gain in CB configuration is always less than 1.

### Solution:

The detailed solution to the question, the value of current gain in CB configuration is always_____ is provided here.

A common base configuration is basically regarded as a current-controlled current source (CCCS) or current amplifier which behaves like a current buffer whose current gain is less or close to unity. It provides higher voltage gain. The power gain of the common base configuration is nearly equal to the voltage gain.

Therefore, the value of current gain in CB configuration is always less than 1. Hence, Option (A) is the correct answer.
