Abstract
The utility model provides an electrical conductivity demonstration device for conductors and non-conductors, which belongs to a teaching demonstration device, particularly relates to a teaching demonstration device used for demonstrating electrical conductivity of the conductors and the non-conductors, and is convenient for students to understand and fine in teaching effect. The electrical conductivity demonstration device for conductors and non-conductors comprises a battery holder provided with batteries, and is structurally characterized in that one output end of the battery holder is connected with a first conducting metal clip through a conducting wire via a bulb, and another output end of the battery holder is connected with a second conducting metal clip through a conducting wire.
Description
Technical field:
The utility model is to belong to teaching demonstration device, relates in particular to a kind of teaching demonstration device that is used to demonstrate conductor and nonconductor electric conductivity.
Background technology:
At present, in junior middle school's teaching,, only rely on teacher's oral explanation still not about the apparatus for demonstrating of conductor and nonconductor electric conductivity; The student beyonds one's depth, and can not give full play to students'interest in learning, and teaching efficiency is bad.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of student of being convenient to understands, teaching efficiency is good conductor and nonconductor electric conductivity apparatus for demonstrating are provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises the battery case with battery, its structural feature is that an output terminal of battery case links to each other with first conducting metal folder through bulb by lead, and another output terminal of battery case links to each other with second conducting metal folder by lead.
The beneficial effects of the utility model:
Because an output terminal of battery case of the present utility model links to each other with first conducting metal folder through bulb by lead, another output terminal of battery case links to each other with second conducting metal folder by lead; The teacher just can illustrate conductor and idioelectric electric conductivity by the situation of lighting of bulb of the present utility model in explanation conductor and nonconductor electric conductivity, not only be convenient to student's understanding, and can give full play to students'interest in learning.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment:
The utility model comprises the battery case 5 with battery 6, and an output terminal of battery case 5 links to each other with first conducting metal folder 7 through bulb 4 by lead 1, and another output terminal of battery case 5 links to each other with second conducting metal folder 3 by lead 1.
During use, place first conducting metal to press from both sides between 7 and second conducting metal folder 3 material to be detected 2 and just can demonstrate.If material to be detected 2 is a conductor, then bulb 4 is lighted; If material to be detected 2 is a nonconductor, then bulb 4 is not lighted.
