Objective: Demonstrate the electric current generated by the motion of charged droplets of water
Electric current arises due to an amount of charge being transported during a given interval of time. A flow of current can be simply illustrated with the help of charged droplets of water. In order to carry out the measurement, a burette and a Faraday cup connected to an electrometer will be used. The charge accumulated in the Faraday cup in a certain period of time is measured with the help of the voltage which drops across the capacitor. This allows the charge per droplet and the current to be determined.
