Description
Technical field
The utility model relates to a kind of physical teaching aid, specifically a kind of series-parallel circuit demonstration teaching aid.
Background technology
At present, teacher of physics is when giving lessons, about the knowledge of electrical circuit aspect, be by teacher according to awarded content and experiment content mostly, blackboard draw circuit and sees to student, or by teacher the required experiment components and parts used to be placed on dais and to operate, demonstration is seen to student, blackboard draws circuit diagram and demonstrates to student, too abstract, not directly perceived, be not easy the interest having excited student; And components and parts used for experiment are placed on dais and demonstrate to student, components and parts used are more, and it is very scattered, inconvenient teacher carries and stores, especially wire, usually can be intertwined, very large trouble is brought to teacher's teaching, when operating because the plane at place, dais is parallel with student's sight line, or a little more than the sight line of student, often Most students does not see the connected mode of Chu's circuit; This form of teaching is not easy the interest having excited student, also reduces the efficiency of teaching of teacher simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of series-parallel circuit demonstration teaching aid, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of series-parallel circuit demonstration teaching aid, comprises case lid, metallic channel, casing, miniature bulb, magnetic stripe, switch, draw-in groove, binding post, power supply, reometer, resistance, battery case, turn buckle, adhesive tape, wire, crocodile clip and support; Described case lid is provided with metallic channel, battery case and turn buckle; Miniature bulb, switch, binding post, power supply, reometer and resistance is provided with in described casing; Front baffle plate and the two sides baffle plate of described casing are provided with magnetic stripe; Described front baffle plate is provided with draw-in groove; Described metallic channel is provided with adhesive tape; Described wire two ends are connected with crocodile clip.
As further program of the utility model: the back side of described casing is provided with support.
As further program of the utility model: described support is reversible supporting frame.
As further program of the utility model: described miniature bulb, switch, binding post, power supply, reometer and resistance are all fixed on casing.
Compared with prior art, the beneficial effects of the utility model are:
What all components and parts were all neat is fixed on teaching aid, and wire is placed in special groove, and avoid wire and be wound around, teaching aid can prop up by support, facilitates observation of students; The utility model simplicity of design, is convenient for carrying, and the teaching for teacher reduces a lot of trouble.
