Exam-style question
Try this first
Explain when ohmic and non-ohmic behavior applies in electrical components. Which type of behavior is observed in a filament lamp?.
Model answer
What a good answer should say
- Ohmic behavior applies to components like resistors, where the current remains proportional to the voltage.
- Non-ohmic behavior is observed in components like filament lamps, where the current increases at a decreasing rate as the temperature rises, leading to a non-linear I-V characteristic.
Explanation
Why this works
This question assesses the ability to apply theoretical knowledge to practical examples. By explaining the conditions under which each type of behavior occurs and identifying the behavior of a filament lamp, students show their understanding of circuit components and their characteristics.
