Elementary charge and Millikan experiment Benefits Learning objectives - Electric field
- Viscosity
- Stokes' law
- Droplet method
- Electron charge
Principle Charged oil droplets subjected to an electric field and to gravity between the plates of a capacitor are accelerated by application of a voltage. The elementary charge is determined from the velocities in the direction of gravity and in the opposite direction. Tasks - Measurement of the rise and fall times of oil droplets with various charges at different voltages.
- Determination of the radii and the charge of the droplets.
