The early effect in a bipolar junction transistor is caused by

  • A. Fast turn on
  • B. Fast turn off
  • C. Large collector-base reverse bias
  • D. Large emitter-base reverse bias

Answer: C. Large collector-base reverse bias

Explanation: Large collector-base reverse bias widens the collector depletion region, reducing base width (Early effect).
