Question

In a certain circuit, a transistor has a collector current of 10 mA
and a base current of 40 u A. What is the current gain of the
transistor?

(Answer with solution) ​

Answer 1

Answer:

250 µA IS THE CORRECT ANSWER

Explanation:

Answer 2

Answer:

The correct answer is equal to 1000.

Explanation:

The Transistor is a device that regulates the flow of the current and voltage. This is one of the basic building blocks of modern electronics. It contains three-terminal names emitter, base and collector.

Given:

$I_{C}=0.01A\\ I_{B}=0.00001A$

$I_{C}$ denotes as the collector current.

$I_{B}$ denoted as the base current.

$\beta$ denoted as the current gain.

By the equation,

$\beta =\frac{I_{C}}{I_{B}} \\\beta =\frac{I_{0.01}}{0.00001} \\\beta =1000$

So, the current gain is equal to 1000.
