  1. In the transistor circuit shown in the figure, collector-to-ground voltage is +20 V. Which of the following is the probable error?

    1. Collector-emitter terminals shorted
    2. Emitter to ground connection open
    3. 10 kΩ resistor open
    4. Collector-base terminal shorted
Correct Option: B

For collector to ground which is the same as emitter terminal to read full supply voltage at 20 V, no current should be drawn and this can happen if emitter to ground connection is open as then there will be neither IH or IC.
