Millikan Lab Summary

Lab Partner: Boleszek
Essential lab procedures were takne from the manual for the PASCO scientific Model AP-8210 "Millikan Oil Drop Apparatus" which can be found online here: 8210 Manual.pdf

Purpose

To reproduce a measurement of the charge of an electron

Procedure

The procedure is fairly well shown in our lab notes and in the 8210 manual bookmarked above. It takes a bit of time to get used to the device, but it is not too difficult to acquire decent data as is shown by our results.

Calculations

Methods for calculating the charge are well documented in the apparatus manual pages 2 and 9. These techniques were used without modification. I carried them out in Mathcad

Atmospheric pressure data was aquired once per day

Viscosity of air was calculated with the help of an online viscosity calculator
