Problems solved by technology
[0002] In the middle school physics class, the teaching of "circuit" is an important content, but it is difficult for students to grasp the characteristics of series and parallel circuits, and it is difficult to understand the direction of current in the circuit, especially the relationship between the direction of current and the direction of electron movement. clear
However, the current and the direction of the current in the circuit cannot be seen or touched by students. They can only listen to the teacher's lectures and understand with imagination. They cannot form perceptual knowledge, and the teaching effect is mediocre.

The invention provides a visual circuit device comprising an insulating substrate and a demonstration device. The demonstration device is arranged on the insulating substrate. The beneficial effects of the visual circuit device are that the bottom parts of a demonstration device switch, an electrical appliance, an ammeter, a slide rheostat, a power supply and a microcomputer controller are provided with magnets, the components can be adsorbed on the insulating substrate equipped with a thin iron plate and all the components can move, the components can be connected by visual lines to form multiple different required series, parallel or series-and-parallel circuits, and students can directly observe the current on the lines, the current direction, the electron movement direction and the change of the speed size with their naked eyes so that the visibility and the interestingness of learning can be enhanced, the students are enabled to easily understand the relationship between the current direction and the electron movement direction and master the characteristics of the series, parallel and series-and-parallel circuits and the use method of the rheostat and the ammeter and thus the doubled teaching effect can be obtained.
Description
【Technical field】 [0001] The invention relates to a circuit, in particular to a visualization circuit device for teaching. 【Background technique】 [0002] In the middle school physics class, the teaching of "circuit" is an important content, but it is difficult for students to grasp the characteristics of series and parallel circuits, and it is difficult to understand the direction of current in the circuit, especially the relationship between the direction of current and the direction of electron movement. clear. However, students can't see the current and the direction of the current in the circuit. They can only listen to the teacher's lecture and understand it by imagination. They can't form perceptual knowledge, and the teaching effect is mediocre. [0003] If students can directly observe the current on the circuit, the direction of the current and the direction of electron movement, students can easily grasp the relationship between the direction of current and the d...
