(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Describe how you would show experimentally that the charge stored on a 220 µF capacitor is proportional to the potential difference across the capacitor for a range of potential differences between 0 and 15 V. Your answer should include a circuit diagram.

2. Relevant equations

3. The attempt at a solution

- charge the capacitor for a given Voltage, V

- ensure the capacitor is charging at a constant rate by varying the resistance of the variable resistor --> ensures current remains constant

- Q=It (current * time take for capacitor to charge)

- capacitor is charged when V on meter = V of supply

- Q/V = constant for range of values of V

Is this method correct - would it work?

p.s: I am aware my diagram is not very well drawn - i will obviously improve this in the exam
