THEORY. In this experiment you will use tiny droplets of oil. When these droplets fall under the influence of gravity it takes them only a few milliseconds to reach a terminal (constant) speed vf, where the downward force of gravity is balanced by the upward drag force from the air.
This experiment first described by [Millikan, 1913] is based on the fact that different forces act on an electrically charged oil drop moving in the homogeneous electric field of a plate capacitor (Figure 1).

Millikans oil-drop experiments are justly regarded as a major contribution to twentieth-century physics [1, 2]. They established the quantization of electric charge, the existence of a...
This experiment first described in 1913, is based on the fact that different forces act on an electrically charged oil drop moving in the homogeneous electric field of a plate capacitor (Fig.1). Going through the capillary of the atomizer, the oil droplets acquire electric charge due to friction. The effect is known as triboelectri c charging.
In Millikan’s experiment, oil drops are sprayed from a nozzle into a volume between two closely-spaced horizontal metal plates that are insulated from each other. The drops can be kept from falling by applying a potential difference between the plates. 1. When the oil drops are sprayed into the volume they are already electrically charged.
