An Electronic charge on a drop of oil can be calculated by this apparatus.
Principle :
An oil drops and g be the acceleration due to gravity. If the drop is left to itself in air, it moves downwards due its weight mg. Now, since there exists a relative motion between the drop and the medium, the viscous force acts upwards. In the initial stages of motion, its velocity increases due to gravity; viscous force also increases. When the voltage by a Power Supply is applied, this changes the velosity of drop. The direction can be changed by reversing switch provided.
Specifications :
Telemicroscope : Achromatic lenses with focussing.
Microscope Lamp House, Automizer Power Supply.
