The invention relates to a direct-current circuit dynamic display device comprising a display device and a motion device; the display device comprises a mounting plate, a mounting groove is formed inthe mounting plate, a magnetic turning column is arranged in the mounting groove, a display plate is arranged above the mounting plate, an observation groove is formed in the display plate, and a battery groove, a switch and a bulb are further arranged on the display plate; the motion device comprises a placement box, a partition plate is arranged in the placement box, a bottom plate is arranged at the bottom of the placement box, through holes are formed in the partition plate, a motor rotating shaft is arranged in one through hole, bearings are arranged in the other through holes, rotating shafts are arranged in the bearings, synchronous wheels are arranged on the rotating shafts, synchronous belts are arranged on the synchronous wheels, the synchronous belts are provided with metal support plates for mounting permanent magnet steel, when the permanent magnet steel moves, the magnetic turning column located right above is turned over to simulate current flow, and the metal support plates trigger a proximity switch to control lighting and extinguishing of the bulb. According to the direct-current circuit dynamic display device disclosed by the invention, two faces of different colors of the magnetic turning column are turned over, so that the abstract concept of the current in the circuit is visually reflected.
Description
technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a dynamic display device for a DC circuit. Background technique [0002] A circuit is a conductive loop composed of wires and electrical and electronic components. Adding a power supply to the input end of the circuit causes a potential difference at the input end, and the circuit can work when it is connected. Scientifically, the amount of electricity passing through any cross-section of a conductor per unit time is called the current intensity, or current for short. Electrically, the direction in which positive charges flow is defined as the direction of current flow. [0003] The existence of the current current is only tested by the deflection of the ammeter. [0004] However, testing with ammeter deflection still has the following disadvantages: [0005] 1. It is difficult to understand such an invisible and intangible abstract concept as electric current; ...
