See Enlarge Click to Enlarge Millikan Apparatus (0846) Specifications : Dimensions: 26 x 20 x 9 cm, Mains supply: 110 V / 230 V, 50 ? 60 Hz. The quantization of electric charge is still as mysterious as it was over 90 years ago when it was discovered by Robert Millikan in his groundbreaking oil-drop experiment. With this apparatus all the obstacles to the focus of the experiment are removed. The charge of an electron will be measured by observing the rising and falling of latex microspheres in an electric field. LAWS & PRINCIPLES INVESTIGATED : • Electric charge • Air buoyancy • Air viscosity • Reynolds number.
