It is small.Resistance value is unalterable to be known as fixed resister.Resistance value variable referred to as potentiometer or variable resistance.Ideal resistor
It is linear, i.e., directly proportional to additional instantaneous voltage by the transient current of resistor, the variable resistance for dividing, naked
On the resistive element of dew, one or two removable hard contact pressed against.Contact position determines the resistance between resistive element either end and contact
Value.
The resistance value size of resistive element generally also has cross-sectional area related with temperature, material, length, and gauge resistor is by temperature
The physical quantity that degree influences size is temperature coefficient, is defined as resistance value changed percentage when temperature often increases 1 DEG C.Electricity
The main physical characteristics of resistance are to become electric energy as thermal energy, as soon as can also say it is a dissipative cell, electric current generates interior energy by it.Electricity
Resistance usually plays partial pressure, shunting in circuit.For signal, exchange can pass through resistance with direct current signal.
Traditional design uses single resistance, and front internal electrode size is wide, caused by causing product adjustment location point difference
Resistance difference is big, causes product precision low.
