Abstract
The utility model discloses an electrics teaching aid, which comprises a substrate. A semiconductor module and chilling plates are arranged on the substrate. The two ends of the semiconductor module are connected with each other to form a loop, and an amperemeter is arranged in the loop. Due to the arrangement of the chilling plates, a temperature difference is generated between the two ends of the semiconductor module. The current generated in the loop enables the pointer of the amperemeter to rotate or the light emitting tube of the amperemeter to go on, so that the thermoelectric power generation is intuitively demonstrated. Meanwhile, the interest of students in learning electronics Information is improved. The electrics teaching aid has the advantages of simple structure and low cost.
Description
Technical field
The utility model relates to a kind of teaching aid, especially relates to a kind of electricity teaching apparatus.
Background technology
In order to improve the quality of teaching, improve the student to the interest of electricity knowledge, the Active Learning electricity knowledge, electricity is tested, demonstration is extremely important.By the Teaching aid for electricity Demonstrator Trials, can very intuitively allow the concrete perception of student, reduce the difficulty of students abstract concept, help it to form clear and definite concept, develop its observation ability and thinking ability, improve student's learning interest and enthusiasm.But existing electricity test teaching aid seldom, is difficult to satisfy the at present demand of teaching.
The utility model content
Technical problem to be solved in the utility model provides a kind of electricity teaching apparatus, its objective is the ocular demonstration thermo-electric generation, improves the student to the learning interest of electricity knowledge.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of electricity teaching apparatus, comprise substrate, and described substrate is provided with semiconductor module and cooling piece, described semiconductor module two ends are connected and form the loop, are provided with reometer in the loop.
Described substrate is provided with slide rail, and semiconductor module one end is located at the slide rail end, and cooling piece is located on the slide rail.
Be provided with gauge tap in the loop on the described substrate, the luminotron fast interface that is provided with in parallel with gauge tap.
The utility model compared with prior art, have the following advantages: by cooling piece the semiconductor module two ends are produced temperature difference, ammeter pointer is rotated the electric current that produces in the loop or luminotron lights, demonstrate intuitively thermo-electric generation, improve the student to the learning interest of electricity knowledge, and simple in structure, cost is low.
Description of drawings
The below makes brief description to the expressed content of each width of cloth accompanying drawing of this instructions and the mark among the figure:
Fig. 1 is the utility model electricity teaching apparatus organigram.
Among the figure: 1. substrate, 2. slide rail, 3. cooling piece, 4. power connection, 5. semiconductor module, 6. reometer, 7. luminotron fast interface.
Embodiment
