The I-V characteristics of an electronic device are shown in the figure. The device is: (a) a solar cell (b) a transistor which can be used as an amplifier (c) a diode which can be used as a rectifier (d) a zener diode which can be used as a voltage regulator

Answer: (d). The curve conducts in forward bias and shows a sharp reverse breakdown where the voltage stays almost constant. Constant voltage over a large current range at breakdown is the Zener property. So the answer is (d) a zener diode used as a voltage regulator.

Show answer and solution

Answer: (d)

The curve conducts in forward bias and shows a sharp reverse breakdown where the voltage stays almost constant.
Constant voltage over a large current range at breakdown is the Zener property.
So the answer is (d) a zener diode used as a voltage regulator.
