Abstract
The utility model discloses a current demonstration teaching appliance belonging to the teaching appliances. The teaching appliance provided in the utility model comprises a lamp socket, a lamp rack and a bulb. The bulb is disposed on a lamp rack, and the bulb as well as the lamp rack is disposed on the lamp socket. A lampshade is covered on an upper part of the bulb, which is connected with a power socket. The utility model is advantageous in that the current directions of the direct current and the alternating current can be visually observed by using the teaching appliance, the learning interests of students can be improved, the understanding of the students can be facilitated, and the academic records of the students can be improved.
Description
Technical field
The utility model belongs to a kind of teaching aid, particularly a kind of electric current demonstration teaching aid.
Background technology
The Physics Learning stage in middle school, constant current and alternating current are required contents, galvanic direction of current is constant to teacher in the classroom, the direction of current of alternating current changes, but how distinguishing the two acquires a certain degree of difficulty, only say principle on the class, not intuitively impression, the student understands very difficult.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective, a kind of electric current demonstration teaching aid is provided, it had overcome in the past just theory teaching, to cannot see impalpable electric current and can watch intuitively by this teaching aid the direction of current of direct current and alternating current, improve student's learning interest, help the student to understand, help the raising of Students ' Learning achievement.
The purpose of this utility model is achieved through the following technical solutions: a kind of electric current demonstration teaching aid, it is characterized in that: it comprises lamp socket, lamp bracket and bulb, and bulb is installed on the lamp bracket, and bulb and lamp bracket are installed on the lamp socket, bulb top spiral-lock lampshade, bulb connects supply socket.
Advantage of the present utility model and beneficial effect are: can watch intuitively the direction of current of direct current and alternating current by this teaching aid, improve student's learning interest, help the student to understand, help the raising of Students ' Learning achievement.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: 1-lamp socket, 2-bulb, 3-lamp bracket, 4-lampshade, 5-supply socket, 6-style of the shoe magnet.
Embodiment
Embodiment: as shown in the figure, a kind of electric current demonstration teaching aid, bulb 2 are installed on the lamp bracket 3, bulb 2 is installed on the lamp socket 1 with lamp bracket 3, bulb 2 top spiral-lock lampshades 4, and bulb 2 connects supply socket 5, supply socket directly is inserted on the 220V AC power, and at this moment, bulb is luminous, then style of the shoe magnet 6 is placed on the lampshade, the magnet direction is constant, at this moment, just see that filament is under the permanent magnet magnetic field action, because direction of current changes, make filament shake, Here it is observable alternating current; If on the battery of electric vehicle direct supply, filament shakes a little and makes a movement with power plug, stable immediately, do not rock.
