The input impedance of a transistor connected in___________arrangement is the highest?
Correct answer: B. common collector
- A. common emitter
- B. common collector
- C. common base
- D. none of the above
Explanation
The common-collector circuit has the highest input impedance because its input is applied at the transistor base and its emitter follower action gives a large effective resistance. Common-base configuration has the lowest input impedance, while common-emitter lies between them.
