Description
Technical field
The utility model relates to electronic technology field, particularly relates to a kind of many valued resistor box.
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.
General and the temperature of the resistance value size of resistive element, material, length, also have cross-sectional area relevant, the physical quantity of gauge resistor temperature influence size is temperature coefficient, and it is defined as the percentage that when temperature often raises 1 DEG C, resistance value changes.The main physical characteristics of resistance is power transformation can be heat energy, and also can say that it is a dissipative cell, electric current is energy in it just produces.Resistance plays dividing potential drop, shunting in circuit usually.Concerning signal, exchange and can pass through resistance with direct current signal.Generally each only has a kind of resistance to existing resistance, resistor will be caused more, cause confusion when the multiple resistance of needs, the use of impact experiment.
