Exam-style question
Try this first
If a capacitor has a capacitance of 5 µF and is connected to a 10 V battery, what is the charge stored in the capacitor? Scenario focus: field energy in a distinct A-Level Physics fields context; identify the field quantity, source, direction, and unit before selecting the answer.
- A.50 µC
- B.100 µC
- C.200 µC
- D.500 µC
Model answer
What a good answer should say
- 50 µC
Explanation
Why this works
The correct answer is 50 µC. This is correct for Capacitance because the stem is testing field energy; 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.
