The base resistor method is generally used in ________________?
Correct answer: B. Switching circuits
- A. Amplifier circuits
- B. Switching circuits
- C. Rectifier circuits
- D. None of the above
Explanation
The base-resistor method gives poor bias stability because collector current depends strongly on transistor beta, so it is mainly suitable for switching, where the transistor is driven between cutoff and saturation. Amplifier biasing normally uses emitter or voltage-divider stabilization.
