Worked Solution & Example Answer:A student investigated the e.m.f - Edexcel - A-Level Physics - Question 7 - 2023 - Paper 1
Step 1
Which row of the table gives the quantities plotted?
Answer
To answer this question, we need to analyze the graph provided.
The graph likely represents a relationship between the terminal potential difference and the current. In typical experiments involving a battery, the terminal potential difference decreases as the current increases due to the internal resistance of the battery.
Based on this understanding, we can match the axes:
- The y-axis represents the terminal potential difference which is shown on the vertical axis of the graph.
- The x-axis represents the current which is displayed on the horizontal axis of the graph.
Referring to the table:
- Option D lists the terminal potential difference on the y-axis and current on the x-axis, which matches our interpretation of the graph.
Thus, the correct answer is D.
