Notes
1.Install a graphic card and soft ware (purchase separately) to model LADP-12 oil drop apparatus and the real-time sample data collection experiment may start immediately (see “Brief Introduction to the Operation of Model LADP-13 Millikan Oil Drop Apparatus”).
2. Because of the defective quality of toggle switches this experiment has replaced such switches with programmable electronic switches.
3. Since the tendency of physics experiments’ teaching reform is to construct digital physics labs, this experiment has left rooms for such tendency. It can be improved very easily to suit for the digitalization tendency.
