The utility model discloses a set up the resistance board of the different resistances of a plurality of, 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
This utility model relates to electrical and electronic technology field, particularly relates to a kind of experiment resistance.
Background technology
Resistor is the most typically directly referred to as resistance.It is a current limiting element, will
After resistance connects in circuit, the resistance of resistor is fixing usually two pins, and it can
Limit the size of current by its institute's chord road.Resistance is unalterable is referred to as fixed resistance
Device.What resistance was variable is referred to as potentiometer or rheostat.Preferably resistor is linear
, i.e. it is directly proportional to additional instantaneous voltage by the transient current of resistor.For dividing potential drop
Rheostat.On exposed resistive element, pressed against one or two and can move hard contact.
Contact position determines the resistance between resistive element either end and contact.
Terminal voltage and electric current have and determine functional relationship, embody electric energy and are converted into the two of other form abilities
End-apparatus part, represents with letter r, and unit is ohm Ω.Practical devices such as bulb, electric heating
Silk, resistor etc. is all represented by resistor element.
The resistance value size of resistive element is general and temperature, material, length, also cross section
Long-pending relevant, the physical quantity of gauge resistor temperature influence size is temperature coefficient, and it is defined as
The percent that when temperature often raises 1 DEG C, resistance value changes.The main physical characteristics of resistance
It is that power transformation can be for heat energy, it is possible to saying that it is a dissipative cell, electric current is in it just produces
Energy.Resistance the most generally plays the effect of dividing potential drop, shunting.For signal, exchange with
Direct current signal can pass through resistance.
Typically only a kind of resistance of resistor used in teaching process, so can cause electricity
Resistance device quantity is 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, it is provided that Yi Zhongshi
Test and use resistance.
This utility model is to be achieved through the following technical solutions:
A kind of experiment resistance, including resistance shell, described resistance enclosure is provided with first
Resistance plate, the second resistance plate and the 3rd resistance plate, described first resistance plate, the second resistance plate
And it is arranged in parallel between the 3rd resistance plate, described first resistance plate, the second resistance plate and the 3rd
Between resistance plate, resistance is different, described first resistance plate, the second resistance plate and the 3rd resistance plate

2, the second resistance plate 3 is fixing with the 3rd resistance plate 4 two ends is connected.Described first resistance plate
2, it is arranged in parallel between the second resistance plate 3 and the 3rd resistance plate 4, described first resistance plate
2, between the second resistance plate 3 and the 3rd resistance plate 4, resistance is different, described first resistance plate
2, the second resistance plate 3 and the 3rd resistance plate 4 two ends are equipped with utility outlets 5, wherein said
Utility outlets 5 model is the most identical.
It is equipped with resistance on described first resistance plate the 2, second resistance plate 3 and the 3rd resistance plate 4
Value label 6, wherein said resistance label 6 is pasted onto first resistance plate the 2, second resistance plate 3
With on the 3rd resistance plate 4 surface.By arranging the resistance plate of several different resistances, so
The resistance of different resistances is installed together, it is to avoid the resistor of different resistances is because of quantity too
Many and affect the carrying out of experiment.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this practicality
Novel, all made within spirit of the present utility model and principle any amendment, equivalent replace
Change and improvement etc., within should be included in protection domain of the present utility model.
