Exam-style question
Try this first
Describe how the I-V characteristic of a diode differs from that of an ohmic conductor.
Model answer
What a good answer should say
- The I-V characteristic of a diode is non-linear, showing a threshold voltage for conduction, while an ohmic conductor has a linear relationship where current is directly proportional to voltage across all values.
Explanation
Why this works
This answer effectively contrasts the behaviors of diodes and ohmic conductors, testing the ability to distinguish between different electrical components. Understanding these differences is essential for analyzing circuit behavior.
