Junction Transistor

In common emitter mode of transistor, the d.c. current gain is 2020, the emitter current is 77 mA. The collector current is

Show answer and solution

Answer: (b)

  1. α=β1+β=2021\alpha = \dfrac{\beta}{1+\beta} = \dfrac{20}{21}
  2. IC=αIE=2021×7=203I_C = \alpha I_E = \dfrac{20}{21} \times 7 = \dfrac{20}{3} mA.
  3. So the answer is (b) 203\dfrac{20}{3} mA.
