Suggested Improvements:
The investigation could have yielded more accurate results if the following modifications were made in future:
1. To deal with the first problem, the charging process of the capacitor could be filmed using the same method as with the discharge process. The time could be determined more accurately when reviewing the video footage.
2. The error of measuring time between charging and discharging could be avoided by setting up the camera to film the voltmeter continuously, thus allowing the position of the switch to be changed very quickly.
Conclusion:
The aim of the experiment was to investigate the relationship between the capacitor’s discharge time and current. The theory that current decreases exponentially against time was confirmed through experimentation.…
