Exam-style question
Try this first
What does the charging curve of a capacitor typically look like?.
- A.Linear increase followed by a plateau
- B.Exponential increase approaching a maximum voltage
- C.Constant voltage over time
- D.Exponential decrease to zero
Model answer
What a good answer should say
- Exponential increase approaching a maximum voltage
Explanation
Why this works
The charging curve of a capacitor shows an exponential increase in voltage as it approaches the maximum voltage, which is characteristic of how capacitors charge over time.
