2.10 resistance
Resistance (usually "R") is a physical quantity that indicates the size of the conductor on the current obstacles in physics. The greater the resistance of the conductor, the greater the hindrance effect of the conductor on the current. Different conductors and resistors are generally different. Resistance is a characteristic of the conductor itself. The resistance can cause changes in electronic circulation. The smaller the resistance, the greater the electronic circulation, and vice versa. There is no resistance in the superconductor.
The resistance of different conductors can be divided into two types according to their properties. One is called linear resistance or Ohm resistor to meet the law of Ohm; the other is called non -linear resistance and does not meet the law of Ohm. The countdown 1/R is called a conductive, and it is also the physical quantity to describe the conductive performance of the conductive conductivity. It is represented by G.
2.10.1 The role of resistance
In the electronic system, the role of resistance is very important. Except for the standard resistance of the component, other components have resistance values that can affect circuit voltage and current.
The fixed resistor and variable resistors are used in the motor vehicle electronic system. The fixed resistor is divided into a wire winding device and a metal membrane resistor.
2.10.2 What is the resistor of the conductor?
The resistance of the conductor depends on the size, resistance and temperature of the conductor. The longer the conductor, the greater the resistance value. The larger the cross section of the conductor, the smaller the resistance value. Different materials of the same size are different.
2.10.3 What is the resistance used as a component?
(1) The resistance value of the resistance indicates that because the resistance of the wire will adversely affects in most cases, the electronic system usually needs to limit the circuit current within a specific limit. The corresponding types and size resistance are used as components according to the specific purpose. Because the resistance size is usually small and does not indicate or it is difficult to see the resistance value, the color ring is usually used to indicate the resistance value.
Each color represents a specific resistance, so the resistance value can be obtained by calculating the total number of color ring numbers. The resistance value indicated on the resistance is only suitable for conditions at 20 ° C. The reason why this limit is because the resistance of all materials will change with temperature .
2.10.4 What is a mechanical variable resistor?
Mechanical variable resistors are divided into potentiocators and fine -tuning potentiometers.
The resistance value of the potentiometer can be changed at any time, and the resistance value of the fine -tuning potential can only change occasionally when adjusting. The potentiometer is installed in the dust -proof cover and has a shaft.
The potentiometer is used for length measurement.
The contacts of the potentiometer are related to the length of the test. The changes of the resistance can be measured by the length. The potentiometer can also be used as an angle sensor. In this case, there is a fixed relationship between the voltage drop between the rotation angle and the voltage drop on the potentiometer.potentiometer circuits for measuring voltage.
