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 out all calculations in Mathcad as I expected to be able to save that to a file that could be directly uploaded as part of this page. It turns out that MHT files are prohibeted on wiki, so I have placed it in a word document instead. The calculations and summary are located there.


As a final note, viscosity of air was calculated with the help of an online viscosity calculator
