- \(\frac{\Delta I_C}{\Delta I_B}\)
- \(\frac{\Delta I_B}{\Delta I_C}\)
- \(\frac{\Delta I_E}{\Delta I_B}\)
- \(\frac{\Delta I_B}{\Delta I_E}\)
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Define.
Current gain compares the output current (collector) to the input current (base).
Step 2: Match.
This is $\Delta I_C/\Delta I_B$, option (A).
Final Answer:
Option (A). \[ \boxed{\frac{\Delta I_C}{\Delta I_B}} \]
