The input impedance of a transistor is___________?
Correct answer: B. low
- A. high
- B. low
- C. very high
- D. almost zero
Explanation
A transistor's input impedance is generally low to moderate, especially compared with a field-effect transistor, because its input junction is forward biased in normal operation. Thus the usual basic-transistor MCQ answer is low.
