Objective: Measure the electric field in a plate capacitor using the electric field meter
The electric field meter can be used to measure the electric field within a plate capacitor directly. In this experiment a rotating sectored disc interrupts the electrostatic flux falling on an induction plate, which forms part of a capacitor plate. The voltage pulses that are thereby generated are amplified to give an output voltage, which is then rectified to give a DC voltage that is proportional to the electric field E acting on the induction plate.
