Q158 / 160 · AP EAMCET 2024 (19 May Shift 2) · Physics

When a signal is applied to the input of a transistor it was found that output signal is phase- shifted by $180^{\circ}$. The transistor configuration is

  • A
    CB - configuration
  • Correct answer
    B
    CE - configuration
  • C
    CC - configuration
  • D
    Both CB and CC - configuration

Solution

In common-emitter (CE) configuration of transistor, the phase shifted by output signal from input signal is $180^{\circ}$.

Hence, the correct answer is option: 'B'.
