Q127 / 180 · NEET 2020 (Phase 2) · Physics

A n-p-n transistor is connected in common emitter configuration in which collector voltage drop across load resistance (800 Ω) connected to the collector circuit is 0.8 V. The collector current is

  • A
    2 mA
  • B
    0.1 mA
  • Correct answer
    C
    1 mA
  • D
    0.2 mA

Solution

The voltage drop across load resistance=0.8 V, then from the idea of Ohm's law the current flowing through the collector is, 

IC=VCRC=0.8800=10-3 A=1 mA.

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