Millikan Oil Drop
Equipment
Safety
Set Up
Notes
Day 1
- Worked with Elizabeth Allen
- Went through a safety brief with Dr. Koch and discussed whats going on in this lab
- used several books to get the height just right to view the eyepiece
- Set up the equipment and adjusted the eyepiece suing the focusing wire to get the grid into focus
- Hooked up the multimeter to the what ever to record the current and looked on the chart on the apparatus to find out at what temp that the experiment was being conducted and also found out what voltage is being applied to the capacitor plates
- Put some oil on the plates using the dropper and started to take data by picking out oil drops to watch
- Had some difficulty's in finding the drops and deiced to adjust the focus to find the drops I don't know if this will alter the data but I will calculate the calculations for the first day compared to how using a different way to find the drops on the other day
- Got some data but it was a struggle to find the drops
Day 2
- Worked with Elizabeth Allen again
- Came in and set up the lab. Took readings on the voltage across the plates which was 501.1 volts. We then took a temperature reading using the multimeter and the attached chart.
- Opened the ionization source lever to allow oil in the spray position and sprayed oil in the chamber.
- First try we could not find oil drops. Searched for them with the focus rings, but no luck. David re-calibrated the focus with the probe.and sprayed oil without the small black cover inside .
