Which BJT configuration typically has high voltage gain, high current gain, and a 180-degree phase reversal?

  • ACommon base
  • BCommon emitter
  • CCommon collector
  • DEmitter follower with unity current gain
Report an error
Correct Answer: B. Common emitter
Explanation: The common-emitter configuration provides both voltage and current gain and introduces phase inversion, making it widely used for amplification.
