Resistor

Resistor (usually referred to as resistance) is a basic passive electronic component that limits the flow of current in the circuit and distributes the voltage in the circuit. Its core parameter is resistance value, and its unit is ohm (Ω). Its working principle is based on the resistance characteristics of conductors. By selecting resistors with different materials (such as carbon film, metal film, wire winding, etc.) And structures, it can achieve different resistance values, power levels and precisions, and can play the roles of current limiting, voltage dividing, loading, shunting and damping in the circuit. Resistors can be divided into fixed resistors, variable resistors (potentiometers), sensitive resistors (thermal, photosensitive, piezoresistors, etc.) according to their structure, and different types can meet the circuit requirements of different scenarios such as industrial electricity, consumer electronics, automotive electronics, etc.
