Special Purpose Diodes
The graph given below represents I-V characteristics of zener diode. The part of the characteristics curve that is most relevant for its operation as a voltage regulator is
Show answer and solution
Answer: (d)
- Voltage regulation uses the reverse breakdown region, where current rises sharply while voltage stays nearly constant.
- In the graph this is the steep part in the reverse-bias quadrant, from d to e.
- So the answer is (d) de.
