About this document
STPM Physics Experiment 6 Results by Jason is a document available to read on EtoBox.
This document summarizes the results of a physics experiment measuring the capacitance and time constant of an RC circuit. The experiment discharged a capacitor through a resistor and measured the current over time. Plotting ln(I0/I) vs time yielded a straight line with a gradient equal to -1/RC, allowing calculation of the capacitance (3.37mF) and time constant (20.9s). Sources of error included resistance of wires and devices and reaction time measuring current. Repeating the experiment improved accuracy.
