Overview

Resistors are current limiting components in circuits, with core functions including current limiting protection to prevent excessive current from damaging sensitive components such as LEDs or chips. $r $n voltage divider function: It distributes voltage proportionally in a series circuit to provide suitable operating voltage for different components. $r $n shunt and filtering: balancing current loads in parallel circuits or used for noise filtering in signal processing. $r $n Short lead time Frizlen brand GWAD320 series resistors

Working principle: Ohm's law

Resistors follow Ohm's law (I=U/R), which states that current (I) is proportional to voltage (U) and inversely proportional to resistance value (R). On a microscopic level, electrons collide with atoms in resistive materials to generate thermal energy, thereby hindering the flow of current; The higher the resistance value, the stronger the hindering effect. ‌‌

Main Categories

Fixed resistor: The resistance value is not variable, including:

Carbon film resistor: Low cost, suitable for ordinary circuits (such as household appliances). ‌‌

Metal film resistor: High precision (error ± 0.1%), used in instruments and meters. ‌‌

Wire wound resistor: high temperature resistance, high power, suitable for industrial motors. ‌‌

Variable resistor: The resistance value can be adjusted, such as potentiometers (used for volume control) and variable resistors. ‌‌

Sensitive resistor: The resistance value varies with the environment, for example:

Thermistor: Temperature sensitive, used for overheat protection. ‌‌

Photoresistor: Light sensitive, used in automatic street lights. ‌‌

Two terminals made of resistive materials with a certain structural form that can limit the passage of current in a circuitelectronic component.resistance valueWhat cannot be changed is called a fixed resistor. The variable resistance is calledpotentiometerOr a variable resistor. The ideal resistor is linear, meaning that the instantaneous current passing through the resistor is proportional to the applied instantaneous currentvoltageDirectly proportional. Some special resistors, such asThermistorVaristors andSensitive componentsIts voltage andcurrentThe relationship is non-linear. Resistors are the most commonly used components in electronic circuits, typically formed into different series based on power and resistance values for circuit designers to choose from. Resistors are mainly used in circuits to regulate and stabilize current and voltage, and can be used asshuntandvoltage dividerIt can also be used for circuit matchingloadAccording to circuit requirements, it can also be used foramplifier circuitNegative feedback or positive feedback, voltage current conversion, voltage during input overload, orcurrent protectionComponents, which can also be composed ofRC circuitAs oscillation, filteringbypassDifferential, integral, andtime constantComponents, etc.
