Abstract
The utility model discloses a kind of device of demonstration battery energy, this device comprises base, and the battery, switch, transformer and two the metal touch balls that are positioned at above base, the input end of described switch and battery, transformer is connected in series, and the output terminal of transformer is connected with two metal touch balls.Owing to adopting said structure, directly perceived, lively demonstration can be experienced with little exchange current by after transformer by sense of touch, can produce high voltage.
Description
Technical field
The utility model relates to a kind of physical phenomenon apparatus for demonstrating, particularly a kind of device of demonstration battery energy.
Background technology
Current classroom teaching, lacks by experiencing by sense of touch, with little exchange current by after AC transformer, can produce the demonstration instrument of high voltage.The energy of one batteries has much, how to make full use of it, and only by the explanation of teacher, student imagines, lecture experiment that can not be directly perceived, lively, thus, bring difficulty to teaching.
Summary of the invention
The purpose of this utility model is to provide a kind of directly perceived, lively, apparatus for demonstrating of having sense of touch.
The purpose of this utility model is achieved through the following technical solutions, this device comprises base, and the battery, switch, transformer and two the metal touch balls that are positioned at above base, the input end of described switch and battery, transformer is connected in series, and the output terminal of transformer is connected with two metal touch balls.
During demonstration, when quick Push switch, this battery supply just becomes AC power, and this alternating current, by after AC transformer, will touch ball two and produce high voltage.When people with the hands touches two Metal Ball simultaneously, just have numb sensation.
The beneficial effects of the utility model: directly perceived, lively demonstration can be experienced with little exchange current by after AC transformer by sense of touch, can produce high voltage.
Accompanying drawing explanation
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing
Fig. 1 is schematic diagram of the present utility model
