In a base resistor method, if the value of ß changes by 50, then collector current will change by a factor ___________________?
Correct answer: B. 50
- A. 25
- B. 50
- C. 100
- D. 200
Explanation
With fixed base bias, the collector current is approximately I_C = βI_B, so a change in beta produces a corresponding proportional change in collector current when I_B is fixed. Thus the stated change factor is 50.
