- $1.25 \mu A$
- $\frac{250}{80} \mu A$
- $430 \mu A$
- $250 \times 80 \mu A$
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
The current amplification factor $\beta$ is defined as the ratio of collector current to base current.
Step 2: Formula
$$\beta = \frac{i_{C}}{i_{B}}$$
Step 3: Calculation
$$i_{C} = i_{B} \times \beta = 250 \times 80 \mu A$$
Final Answer: (D)
