Multi-functional electrostatics experimental facility

Abstract

The invention discloses a multi-functional electrostatics experimental facility. The multi-functional electrostatics experimental facility includes a power supply, a controllable device, a first electrode plate, a second electrode plate and a casing, wherein the first electrode plate and the second electrode plate are connected with the power supply through wires and fixed on a support, the controllable device is used for providing uninterrupted charge particles, the charge particles can move in an electric field and form clearly seen motion tracks, the casing forms a closed environment so that the motion of the charge particles is not affected by the outside, and the power supply is an induction generator or a high voltage power supply. The multi-functional electrostatics experimental facility vividly and intuitively proves the existence of electric field forces and enables people to observe the motion and variation tracks of the charge particles in a uniform electric field.

Description

Technical field [0001] The invention belongs to an experimental device, in particular to a multifunctional electrostatic experimental device capable of demonstrating the movement law of charged particles in an electric field and exploring factors related to the capacitance of a parallel plate capacitor. Background technique [0002] At present, "the movement of charged particles in a uniform electric field" is a comprehensive problem of electricity and mechanics in high school physics, and is a key content in teaching. Since there is no demonstration experiment that directly shows the track changes of this movement, it is also a difficult point in teaching. Although the cathode ray tube, electrostatic deflection oscilloscope and other instruments can demonstrate the deflection of the electron beam emitted by the cathode under the action of the electric field force, it can only allow us to imagine the electron movement process by observing the trajectory of the electron beam hitti...

Problems solved by technology

Although cathode ray tubes, electrostatic deflection oscilloscopes and other instruments can demonstrate the deflection of the electron beam emitted by the cathode under the action of the electric field force, they can only allow us to imagine the electron movement process by observing the trajectory of the electron beam hitting the fluorescent screen. The trajectory of electrons in the electric field cannot be observed intuitively
