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).
From an experimental point of view the atom of the chemist was all contained in the facts of definite and multiple proportions in combining powers. For the purposes for which the concept was used, viz. those of chemical combination, the chemical atom is just as much the ultimate unit now as it ever has been.
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.

Millikan oil drop experiment aims at measuring the charge of the electron. It is perhaps the most basic of all atomic physics or so called modern physics laboratory experiments. The arrangement is quite simple and bears a testimony to the ingenuity of Robert Millikan.
