Results: The main source of error in this experiment was the equipment used. The voltmeter has a reported error of +/- 0.01 volts. The other major source of possible error was the galvanometer, which has a +/-10% error. There is no other major source of error as no other measuring equipment was used. All contacts were touched securely and double-checked for small errors.
