Physics Question on Zener Diodes
The I-V characteristics of an electronic device shown in the figure. The device is
A
a solar cell
B
a transistor which can be used as an amplifier
C
a zener diode which can be used as voltage regulator
D
a diode which can be used as a rectifier
Answer
a zener diode which can be used as voltage regulator
Explanation
Solution
The I-V characteristics of the given device show a typical breakdown region where the voltage remains fairly constant while the current increases. This characteristic is a signature of a Zener diode in its breakdown region, which is used as a voltage regulator.
Thus, the correct answer is Option (3).
