  1. Question 1

    Q1. A transistor is operated in common emitter configuration. The collector supply voltage is 10 V and the voltage drop across a resistor of 1 kΩ in the collector circuit is 0.7 V. The collector current is

    • A) 0.7 mA
    • B) 7 mA
    • C) 0.07 mA
    • D) 70 mA

    Answer: 0.7 mA

    Explanation: Ic = Vc / Rc = 0.7 V / 1 kΩ = 0.7 mA.
