Benefits
-Fascination Nobel Prize (Millikan 1923)
-Exact determination of the elementary electric charge
-Compact set-up
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.
