The function and principle of automobile led resistor

1. The function and working principle of automobile warm air resistance. Cars generally dissipate heat into the compartment by recycling the engine coolant, and there is a resistance wire to assist heating.

2. The main use is to stabilize and regulate the current and voltage in the circuit, and secondly, it is also used as a diverter, voltage divider and load. The component that obstructs the flow of current in a circuit is called a resistor (referred to as resistance). There are many kinds of resistors, usually including fixed resistors, variable resistors, sensitive resistors, exhaust resistors, etc.

3. The function of automobile resistance is to limit the current in the circuit. In electronic systems, the role of resistance is very important. In addition to the standard resistance of the component, each other component has a resistance value that can affect the circuit voltage and current.Fixed resistors and variable resistors are used in the electronic system of motor vehicles.

4. There are also capacitors + resistors. It is used to solve the problem of the fault light of the car dashboard when the original halogen bulb is upgraded to LED headlights. The principle is to increase the current of the headlight circuit of the car. After installing the decoder, when the car driving computer self-checks, it detects that the headlight current is normal and the fault light will not turn on, that is, it is decoding.

5. Principle The resistor is composed of three parts: the resistor body, the skeleton and the lead end (the resistor body and the skeleton of the solid core resistor are combined into one), and only the resistance body determines the resistance value.

6. Resistance usually plays the role of voltage division and flow diversion in the circuit. Working principle: The resistor is composed of three parts: the resistor, the skeleton and the lead end, and only the resistor determines the resistance value.

What are the automotive-grade resistors?

Basically, large manufacturers of resistors all have vehicle-standard patch resistors. Manufacturers such as Housheng, Guoju, Fenghua High-tech, Fuxin Electronics, Rome and Panasonic are relatively well-known at present. If necessary, you can compare more and choose according to actual needs.

Ohm. Vehicle-grade resistance is also known as automobile-grade resistance and vehicle-grade resistance. The oil-to-gas vehicle adopts a hybrid configuration, which is different from the pure gas vehicle. The resistance adopts the standard 2-ohm resistance current is just right, so the resistance of the car changed to gas is 2 ohm. Resistance refers to a resistor.

The commonly used resistances of automobile sensors include sliding resistors and liquid level sensors, which correspond to different resistance values according to the height of the liquid level sensor.Temperature control resistance, water temperature sensor is used, and the resistance value changes with the change of temperature.

What are the representations of the resistance on the car?

1. The greater the resistance of the conductor, the greater the obstruction of the conductor to the current. Different conductors generally have different resistances, and resistance is a property of the conductor itself.The resistance of the conductor is usually represented by the letter R, and the unit of resistance is ohm, or ohm for short.

2、A. The direct labeling method x0dx0a marks the main parameters and technical performance of the resistor directly on the resistor in numbers or letters. X0dx0aB. The text symbol method x0dx0a regularly combines words and numbers to represent the main parameters of the resistor.

3. The color representative is defined as follows, brown 1, red 2, orange 3, yellow 4, green 5, blue 6, purple 7, gray 8, white 9, black 0. The above paper is the color definition. The specific calculation method also needs to be divided into the number of resistance color rings, such as the four-ring resistance and the five-ring resistance. The calculation methods are slightly different.

The resistance of the whole car is 500 ohms positiveIs it normal?

1. Two groups of resistors are symmetrically connected to the circuit, among which RRR3 and R4 are large resistors of 500 k ohms, and RandR is. This is a small resistance of 200 ohms. Adjust the on and off of R1 through the switch S, and measure the positive and negative poles of the battery pack twice.

2. At present, there are two kinds of high-voltage lines, one is only a few hundred euros, and the other is more than 10K euros. The automotive high-voltage line, also known as the high-voltage ignition coil or high-voltage package, is to amplify the 12V voltage provided by the battery to 30,000V and release it through the central electrode and side electrode of the spark plug to ignite the mixture.

3. Electric vehicles, the insulation resistance of 550 is 550 ohms. Electric vehicle insulation resistance standardAt the maximum working voltage, the insulation resistance Ry1 of the DC circuit is not less than 100 ohms per volt, and the AC circuit is not less than 500 ohms per volt. The current flowing through the surface of the insulation material in the system. The higher the value, the worse the insulation performance of the system.

4. Ohm. According to the query of CCTV, before the electric vehicle measures the resistance value of the can bus of the ocb on-board diagnosis system, it needs to disconnect the low-voltage battery. The controller at both ends of the can line has a 120-ohm resistor at one end, and two 120-ohm resistors are connected in parallel, so the normal connection resistance of the two wires is 6 0 euros.

5. The general internal resistance of the car start-up battery is a few milliohms: 12v38ah - 20 milliohms, 12v65ah - 80 milliohms, 12v100ah_- 50 milliohms.The internal resistance of the battery is not constant. The filling time and use time are different, and the internal resistance changes differently.

6. The thermistors of car air conditioners are generally thermal resistors of negative temperature, which are usually 5 kilogh, 3 kilog, 5 kiolohm and 10 kg of ambient temperature of 25℃.

How much is the normal resistance of the car computer

Ohm. The terminal resistance only exists in the driving can bus, and the resistance of the maintenance driving computer is 60 ohms. Resistance (usually represented by "R") is a physical quantity, which in physics, represents the magnitude of the conductor's blocking effect on the current.

Ohm. According to the query CCTV, the electric vehicle measurement ocb on-board diagnosis system canBefore the bus resistance value, it is necessary to disconnect the low-voltage battery. The controller at both ends of the can line has a 120-ohm resistor at one end, and two 120-ohm resistors are connected in parallel, so the cross-connection resistance of the two wires is normally 60 ohm.

After adding a magnetic field, when the current and the magnetic field are not oriented towards the crystal axis, the 5K magnetoelectric effect of the resistivity is also different with the intensity of the magnetic field. When a single crystal is affected by a magnetic field, the resistivity of the substance changes, that is, a positive magnetoresistance effect is produced.

The main principle of automotive LED resistors is that when the input voltage is low and close to the positive voltage drop required by the LED, the default current source channel outputs current.

6. Automobile excitation resistor usually refers to a component in the excitation circuit of an alternator, whose function is to control the excitation current of the generator. The excitation current refers to the current through the excitation coil in the alternator. The magnetic field generated by it excites the magnetic field on the rotor, so that the generator generates electrical energy.
