Objective: Measure the electrostatic voltage as a function of the distance between the plates
To increase the distance between the charged plates of a plate capacitor after removing their external conne
ctions, mechanical work must be performed. This can be demonstrated by measuring the resulting increase of the voltage between the plates using an electrostatic voltmeter.
