Replicating Millikan's oil Experiment

1. What must be true about individual elementary charges for your method of determining their values to be valid

2. Why must a large number of values be used to get a reliable answer? What error might result if only a few oil drops were used, or if all the oil drops contained an even number of charges?

3. Millikan's experiment did not determine the precise value of the elementary charge. Explain why this is the case. List possible sources of error for this type of investigation.
