The value of VBE ___________________?
Correct answer: B. Is almost independent of IC
- A. Depends upon IC to moderate extent
- B. Is almost independent of IC
- C. Is strongly dependant on IC
- D. None of the above
Explanation
For a conducting transistor, V_BE changes only logarithmically with collector current, so over normal operating ranges it is treated as approximately constant, around 0.7 V for silicon. It is not completely independent of current, but its dependence is weak.
