About This Lesson
This demonstration shows that charged particles will be attracted up or down when placed between parallel charged plates. It also shows that the electric field can support the weight of the charged particle between the plates. It might already have been shown when discussing how capacitors behave.
A superb resource providing detailed instructions on how to set up Millikan's experiment. Included are links to other websites, health and safety information and explanations of the underlying physics concepts being investigated.
