Function and Application
The Millikan apparatus is used for the precise determination of the elementary charge of electrons.
Using oil droplets suspended in an electric field, the forces acting on individual droplets can be measured, allowing the electron charge to be determined experimentally.
Benefits
- Easy handling due to a clearly structured experimental setup
- Direct visualization of the forces acting on oil droplets enables intuitive learning
- Compatible with standardized power supplies and measuring instruments
