Exam-style question
Try this first
RC discharge graph ? choose the curve feature. Use this to support: Calculate or interpret oscillation period where appropriate.
- A.RC discharge graph: the voltage falls exponentially because charge leaves the capacitor through the resistor for Astables.
- B.RC discharge graph: states a straight-line discharge.
- C.RC discharge graph: uses Hall voltage reasoning.
- D.RC discharge graph: forgets the resistor path.
Model answer
What a good answer should say
- The correct option is RC discharge graph: the voltage falls exponentially because charge leaves the capacitor through the resistor for Astables.
Explanation
Why this works
This is the best answer because the RC discharge graph context requires that exact electronics relationship. The other options are incorrect because they use a different component, reverse the circuit behaviour, or omit the output interpretation required for Astables.
