Question 80Electricity & Electronics - 1st Asst/Chief

The correct answer is B) It is working as it should. When a Zener diode is connected in parallel with a load, and the voltage across the Zener diode remains constant as the current through the load increases, it indicates that the Zener diode is operating as intended. The Zener diode is designed to maintain a constant voltage, known as the Zener voltage, across its terminals as long as the current flowing through it is within its rated range. This property makes Zener diodes useful for voltage regulation applications. The other answer options are incorrect because: A) If the Zener diode was shorted, the voltage across it would be zero, which is not the case in the given scenario. C) If the Zener diode was open, there would be no voltage regulation, and the voltage across the load would fluctuate. D) The Zener diode is regulating the voltage as it should, so it is not failing to regulate.
