Exam-style question
Try this first
A capacitor stores a charge of 12 C at a potential difference of 4 V. Calculate the capacitance of the capacitor. Scenario focus: transformers in a distinct A-Level Physics fields context; identify the field quantity, source, direction, and unit before selecting the answer.
Model answer
What a good answer should say
- The capacitance of the capacitor is 3 F.
Explanation
Why this works
The correct answer is The capacitance of the capacitor is 3 F.. This is correct for Capacitance because the stem is testing transformers; the chosen option keeps the field quantity, source interaction, direction, and unit consistent.
The alternatives are weaker because they mix gravitational, electric, magnetic, orbital, or transformer ideas, or they attach the right number to the wrong physical meaning.
