Abstract
The invention discloses a drop self-excited induced electrification instrument for vividly demonstrating the static electrification phenomenon. The drop self-excited induced electrification instrument comprises a bracket and a water tank fixed at the upper end of the bracket, wherein the bottom of the water tank is connected with a three-way pipe; hoses are correspondingly connected to the other two ends of the three-way pipe; valves are arranged on the corresponding hoses; a glass tube is connected to the lower end of each hose; each glass tube is connected with a metal drum; a metal cup is placed under each metal drum; each metal tube and the corresponding metal cup are connected by a wire; an electroscope is fixed on the bracket.
Description
Technical field
The application relates to a kind of teaching demonstration instrument, and particularly one is dripped self-excitation electrification by influence instrument.
Background technology
By water flow and glass tube electrification by friction, the electric charge circulation gone out in electrostatic induction is piled up, and electrically charged amount gets more and more, and produces the electrostatic electrification of more and more higher potential difference (PD).
Summary of the invention
The application's object is to provide one to drip self-excitation electrification by influence instrument, vivid demonstration electrostatic electrification phenomenon.
The application drips self-excitation electrification by influence instrument, comprise support, be fixed on the tank of pedestal upper end, bottom of gullet connects a three-way pipe, and the another two ends of three-way pipe are connected to flexible pipe respectively, and flexible pipe is provided with valve, flexible pipe lower end is connected with glass tube, glass tube is connected with metal cylinder, and be placed with metal cup respectively immediately below described metal cylinder, both are connected by wire; Described support is fixed with electroscope.
Described electroscope is connected by wire with metal cup.
The application drips self-excitation electrification by influence instrument, and not only structure is simplified, and vivid demonstrating by water droplet flowing and the phenomenon of glass tube electrification by friction, has interest, substantially increases teaching efficiency.
Accompanying drawing explanation
Fig. 1 is that the application drips the structural drawing of self-excitation electrification by influence instrument;
In figure: 1-support; 2-tank; 3-three-way pipe; 4-flexible pipe; 5-valve; 6-glass tube; 7-metal cylinder; 8-metal cup; 9-wire; 10-electroscope.
Embodiment
As shown in Figure 1, the self-excitation electrification by influence instrument that drips comprises support 1, be fixed on the tank 2 of pedestal upper end, bottom of gullet connects a three-way pipe 3, and the another two ends of three-way pipe are connected to flexible pipe 4 respectively, and flexible pipe is provided with valve 5, flexible pipe lower end is connected with glass tube 6, glass tube is connected with metal cylinder 7, is placed with metal cup 8 respectively immediately below metal cylinder, and both are connected by wire 9; Support 1 is also fixed with electroscope 10.
First electroscope 10 is connected with metal cup 8 wire 9, then slowly opens valve 5, make threeway glass tube 3 interruption-forming water droplet stream, just can be observed electroscope 10 soon and open because of charged; Arrest one end of test pencil neon tube with finger, contact any metal cup 8 respectively with the other end, can neon tube luminous be found, which end occurring in neon tube by glistening can judge which kind of electric charge of metal cup band; If flash of light appears at the one end contacted with hand, then tested electrified body positively charged; Survey the voltage between metal cup with high voltage electrostatic voltmeter, the high pressure of ten million volt can be measured.
Claims (2)
1. drip self-excitation electrification by influence instrument, it is characterized in that, comprise support, be fixed on the tank of pedestal upper end, bottom of gullet connects a three-way pipe, the another two ends of three-way pipe are connected to flexible pipe respectively, flexible pipe is provided with valve, and flexible pipe lower end is connected with glass tube, and glass tube is connected with metal cylinder, be placed with metal cup respectively immediately below described metal cylinder, both are connected by wire; Described support is fixed with electroscope.
