Exam-style question
Try this first
A graph of an alternating current (AC) shows a sinusoidal waveform. What does the peak value of the current represent?.
Model answer
What a good answer should say
- The peak value of the current represents the maximum current that flows in one direction during the AC cycle.
Explanation
Why this works
This answer is strong because it accurately identifies the significance of the peak value in an AC waveform. The question tests the understanding of AC characteristics, specifically the interpretation of graph features.
