Official Correct Choice:
Option D: Voltage and current
Concept:

In electronics, the behavior of a component is best understood by observing how the current flowing through it changes as the voltage across it changes.

Solution:

  • The characteristic curve of a diode (often called the V-I curve) is a fundamental graphical representation of its operation.


  • The x-axis conventionally represents the applied Potential Difference (Voltage).


  • The y-axis represents the resulting Current.


  • Therefore, it is a plot between Voltage and current.


Why other options are incorrect:

  • Voltage/Current and time: This would describe an oscilloscope waveform, not a component's internal characteristic curve.


  • Reverse voltage forward voltage: Plotting a voltage against a voltage is nonsensical for describing component behavior.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
