For faithful amplification by a transistor circuit, the value of VBE should_____________for a silicon transistor?
Correct answer: C. Not fall below 0.7 V
- A. Be zero
- B. Be 0.01 V
- C. Not fall below 0.7 V
- D. Be between 0 V and 0.1 V
Explanation
A silicon base-emitter junction needs about 0.7 V forward bias to conduct properly in the active region. If VBE falls below this level, the transistor approaches cutoff and faithful amplification is lost.
