HC Verma Chapter 45 Problem 14

Problem Statement

Transistor has alpha = 0.98. Find beta.

Key Concepts

Transistor alpha-beta relation

Relevant Formulas

beta = alpha/(1-alpha)

Step-by-Step Solution

beta = alpha/(1 – alpha) = 0.98/0.02 = 49.

Final Answer

beta = 49

Tips and Tricks

High alpha (near 1) gives high beta and good amplification.

Common Mistakes

Always use SI units. Check energy conservation accounts for all forms.
