The size of current that limitation passes through its institute's chord road.Resistance value is unalterable to be known as fixed resister.The variable referred to as current potential of resistance value
Device or variable resistance.Ideal resistor is linear, i.e., by the transient current of resistor and additional instantaneous voltage at just
Than.Variable resistance for partial pressure.On exposed resistive element, one or two removable hard contact pressed against.Contact position
Determine the resistance value between resistive element either end and contact.
Terminal voltage has determining functional relation with electric current, embodies the two-terminal device that electric energy is converted into other forms ability, uses word
Female R indicates that unit is ohm Ω.Practical devices such as light bulb, heating wire, resistor etc. are represented by resistor element.
Generally and temperature, material, length, also cross-sectional area are related for the resistance value size of resistive element, gauge resistor by
The physical quantity that temperature influences size is temperature coefficient, is defined as resistance value changed percentage when temperature often increases 1 DEG C.
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.
