Question:
In the case of constant ' \(\alpha\) ' and ' \(\beta\) ' of a transistor ( \(\alpha\) and \(\beta\) are current ratios)
In the case of constant ' \(\alpha\) ' and ' \(\beta\) ' of a transistor ( \(\alpha\) and \(\beta\) are current ratios)
Show Hint
\(\alpha\) is slightly less than 1, \(\beta\) is large.
Updated On: Apr 26, 2026
- \(\beta<1, \alpha>1\)
- \(\beta>1, \alpha<1\)
- \(\alpha = \beta\)
- \(\alpha = \beta^2\)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
\[ \alpha = \frac{I_C}{I_E}, \quad \beta = \frac{I_C}{I_B} \] Step 1: Relation. \[ \beta = \frac{\alpha}{1-\alpha} \]
Step 2: Interpretation.
Step 3: Conclusion. \[ \beta>1, \quad \alpha<1 \]
\[ \alpha = \frac{I_C}{I_E}, \quad \beta = \frac{I_C}{I_B} \] Step 1: Relation. \[ \beta = \frac{\alpha}{1-\alpha} \]
Step 2: Interpretation.
- \(\alpha<1\)
- \(\beta>1\)
Step 3: Conclusion. \[ \beta>1, \quad \alpha<1 \]
