Revision notes on Capacitor Discharge Graphs for the CIE A Level Physics syllabus, written by the Physics experts at Save My Exams. The rate at which a capacitor discharges depends on the resistance of the circuit If the resistance is high, the current will decrease and charge will flow from the capacitor plates more slowly, meaning the capacitor will …
This is a topic in which there is plenty of scope for practical work, and the experiments tend to be reliable. The topic is also rather mathematical; the use of exponential equations can reinforce students'' experience with radioactive decay equations, if this has already been covered. It is unlikely that your students will have met capacitors before unless they …
