First, the factors of the resistance size
The temperature of the resistance is related to the length of the length, and the material and materials are related to the length of the length. Essence Measure the physical quantity of the temperature and temperature that is measured by the resistance of the electrical resistance. Carbon carbon carbon carbon carbon carbon carbon carbon carbon elevation height rise height rising height, height, high, height, the opposite increase of carbon carbon carbon, rising height, height, height, height, height, height, height, height, height, height, height, up, high, elevated Height: The length of the material, the unit m, the S is the unit area, the unit. It can be seen that the material. The size of the material is proportional to the material
: 1 European voltage one current, the gull resistance is also used to control the control current voltage in addition to controlling the control current voltage.
Two -resistance -selection -selection
a. Correct electricity and errors:
Selection of resistance values: The smaller the resistance value of the resistor of the resistor on the principle, the smaller the better.
Error: RC RC circuit circuit needs electric error error. Within 5 %. Instrument.
b. Pay attention to the parameters of electricity:
Rating voltage: When the voltage rated voltage, even if the power requirements, the resistor requirements will damage damage and damage.
Rating: The selected resistor rated the rated power to withstand more than twice the power to ensure the reliability reliability and reliability and reliability and reliability and reliability and reliability of the resistor resistor.
C. To the first pass:
The multi -specifications of general -purpose resistors are large -scale production and production in a large range, the appearance and shape, and the size of the size is available.
D. Selected according to the circuit:
High -frequency: The smaller the distribution, the better, good, good metal resistance, metal resistance and other high -frequency resistance resistance.
Low -frequency: Wind resistance, the resistance is applicable.
Power amplifier circuit, circuit: circuit to high, high, high, high, high height, temperature coefficient, temperature coefficient
Antoupe circuit circuit: There is no strict requirements for pairs, and any type of resistor is applicable and applicable.
e. Selected according to the circuit board. Essence
