Abstract
The utility model relates to an electrical resistance device, including last fixing base, lower fixing base, upward fixing base, lower fixing base are six prismatic structures, it is equipped with a plurality of resistance poles that the resistance is inequality to go up between fixing base, the lower fixing base, the resistance pole is fixing base, lower evenly distributed between the fixing base on drawing together, just it is equipped with the generic interface to be located the fixing base up end in each resistance pole upper end, be equipped with the resistance data plate on each generic interface one side, the inside resistance silk that is equipped with of each resistance pole. The utility model discloses a set up the resistance pole that a plurality of resistances are different, like this with the resistance installation of different resistances together, the going on of the too many and influence experiment of the resistor factor volume of having avoided different resistances.
Description
Technical field
The utility model relates to electrical and electronic technology field, particularly relates to a kind of resistance device.
Background technology
Resistor is generally directly called resistance in daily life.Be a current limiting element, connect by resistance in circuit, the resistance of resistor is fixing is generally two pins, and it can the size of current on its institute's chord road of restricted passage.Resistance is unalterable is called fixed resistor.What resistance was variable is called potentiometer or variable resistance.Desirable resistor is linear, is namely directly proportional to additional instantaneous voltage by the transient current of resistor.For the variable resistance of dividing potential drop.On exposed resistive element, pressed against one or two and can move hard contact.Resistance between contact position determination resistive element either end and contact.
Terminal voltage and electric current have determines functional relation, and embody the two-terminal device that electric energy conversion is other form abilities, represent with letter r, unit is ohm Ω.Practical devices is as bulb, and heating wire, resistor etc. all can be expressed as resistor element.
Resistor used in teaching process generally only has a kind of resistance, and number of resistors can be caused so more, the carrying out of impact experiment.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of resistance device.
The utility model is achieved through the following technical solutions:
A kind of resistance device, comprise upper fixed seat, lower fixed seat, fixed seat, lower fixed seat are six prism structures, the resistance bar that some resistances are not identical is provided with between fixed seat, lower fixed seat, described resistance bar is uniformly distributed drawing together between upper fixed seat, lower fixed seat, each root resistance bar upper end described and be positioned at upper fixed seat upper surface and be provided with general-purpose interface, each general-purpose interface side described is provided with resistance nameplate, and each root resistance bar inside described is provided with resistance silk.
As optimal technical scheme of the present utility model, described resistance bar is fixedly connected with between upper fixed seat, lower fixed seat.
As optimal technical scheme of the present utility model, described general-purpose interface is embedded on upper fixed seat.
As optimal technical scheme of the present utility model, described resistance nameplate is pasted onto on holder upper surface.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model is by arranging the different resistance bar of some resistances, be installed together by the resistance of different resistance like this, the resistor avoiding different resistance affects the carrying out of experiment because quantity is too many.
