The resistance of resistor is fixing usually two pins, and it can limit the size of current by its institute's chord road.Resistance can not
The referred to as fixed resister changing.Resistance variable referred to as potentiometer or rheostat.Preferably resistor is linear, that is,
It is directly proportional to additional instantaneous voltage by the transient current of resistor.Rheostat for partial pressure.In exposed resistive element
On, pressed against one or two removable hard contact.Contact position determines the resistance between resistive element either end and contact.
Terminal voltage and electric current have determination functional relationship, embody the two-terminal device that electric energy is converted into other forms ability, use word
Representing, unit is ohm Ω to female R.Practical devices such as bulb, heating wire, resistor etc. is all represented by resistor element.
The resistance value size of resistive element is general and temperature, material, length, and also cross-sectional area is relevant, and gauge resistor is subject to
The physical quantity that temperature affects 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 are change electric energy is heat energy, also can say that it is a dissipative cell, electric current just produces interior energy through it.
Resistance generally plays partial pressure, the effect of shunting in circuit.For signal, exchange and direct current signal can pass through resistance.
Slide rheostat is one of circuit critical elements, and it can change itself by the position of mobile slide plate
Resistance, thus play the effect of control circuit.In circuit analysis, slide rheostat both can as a fixed value resistance,
Can be used as a resistance-changing resistor.Its operation principle is to change resistance by changing the length accessing circuit part resistive conductor
, thus gradually changing the size of current in circuit.The resistance wire of slide rheostat is usually that fusing point is high, and the big nickel chromium triangle of resistance closes
Gold, metallic rod is usually the little metal of resistance, so when resistance cross section area one timing, resistance wire is longer, and resistance is bigger, resistance
Silk is shorter, and resistance is less.The composition of slide rheostat of the prior art generally comprises binding post, slide plate, resistance wire, metallic rod
With porcelain cylinder etc., because the resistance wire winding zone on porcelain cylinder is not provided with protective cover, easily it is subject to anthropic factor to resistance
Impact, reduces degree of accuracy and the stability of slide rheostat.
Resistor is a current limliting original paper, and transition circuit is played with the effect adjusting resistance.S is used in prior art
Type canoe, when load factor changes, the resistance of resistor can not change according to the actual demand of load.Realizing this practicality
In new process, inventor finds that prior art at least has problems with：Volume is larger, should not process；The resistance of resistor
Value can not change according to the actual demand of load, lead to electric current excessive or heat up too fast.
