Abstract
The utility model discloses a capacitor charge-discharge demonstrator, which relates to the technical field of physical experiment demonstrator. The capacitor charge-discharge demonstrator consists of a panel, an alligator clip, leads, a diode, a capacitor and binding posts, wherein the alligator chip is sequentially and electrically connected with a binding post III, a blue light diode, the capacitor, a power supply and a binding post II through the leads. Compared with the prior art, the capacitor charge-discharge demonstrator needs easily available materials, can present obvious phenomena, can change the brightness of a light emitting diode by changing voltage, replaces a current meter, verifies the definition equation of the capacitor, and is particularly applicable to requirements that the demonstrator is made by self and one people owns one demonstrator, so that the capacitor charge-discharge demonstrator can meet the teaching demands and the thirst for knowledge and the curiosity of students and is a physical teaching aid with a popularization value.
Description
Technical field
The utility model relates to a kind of Physical Experiment demonstration device, is the capacitor charging/discharging demonstration device specifically.
Background technology
In physics teaching, need to say the knowledge of electrolysis condenser.Capacitor is electronic component very common in the electronics, kind, various informative, but its essence and principle of work are basic identical, and the experiment in the teaching material is had relatively high expectations to teaching aid, cannot satisfy the requirement of staff portion, we have obtained good effect to its improvement in long-term teaching.
The utility model content
The purpose of this utility model is for the deficiencies in the prior art, and a kind of capacitor charging/discharging demonstration device is provided.
The purpose of this utility model realizes by following technological means: the capacitor charging/discharging demonstration device, be comprised of panel, crocodile clip, wire, diode, electric capacity and binding post, described crocodile clip is electrically connected with binding post three, blue light diode, electric capacity, power supply, binding post two in turn by wire.
Further, described crocodile clip is electrically connected with binding post three, red diodes, electric capacity, binding post one in turn by wire.
Compared with prior art the utlity model has following obvious advantage: draw materials simple, phenomenon is obvious, can change by changing voltage the brightness of light emitting diode, replaced reometer, verified the definition of electric capacity, being particularly suitable for making by oneself the requirement with the staff portion, having satisfied that teaching requires and student's aspiration to knowledge, curiosity, is a kind of physical teaching aid that promotional value is arranged.
Description of drawings
Fig. 1 is the utility model schematic diagram.
1. panels wherein, 2. crocodile clip, 3. wire, 4. blue light diode, 5. red diodes, 6. electric capacity, 7. power supply, 8. binding post one, and 9. binding post two, and 10. binding post three.
Embodiment
Below in conjunction with description of drawings the utility model is described in further detail:
The use procedure of capacitor charging/discharging demonstration device is: assemble instrument according to schematic diagram, used power supply 7 is two joint dry cells, during the demonstration charging process: crocodile clip 2 is clipped on the binding post 29, can see that the red diodes 5 in the circuit is luminous, carrying out along with charging, brightness is by bright dimmed, until extinguish, charging is finished; At this moment crocodile clip 2 is taken off from binding post 29, and be clipped on the binding post 1, blue light diode 4 is connected, electric capacity 6 discharges, and blue light diode 4 discharges, brightness along with discharge finishes, until extinguish, is finished discharge process by bright dimmed.Phenomenon is obvious, is easy to directly perceived, the perceptual physical principle of understanding.
In a word, the utility model provides the capacitor charging/discharging demonstration device.The above; it only is a part of embodiment of the present utility model; protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
