Product introduction:
WRN-530 WRN-522 WRN-523 WRN-531 WRN-532 K type thermocouples, resistors are commonly referred to as resistors in daily life. It is a current-limiting component. After the resistor is connected to the circuit, the resistance of the resistor is fixed, usually two pins, which can limit the current flowing through the branch connected to it. The resistance that cannot be changed is called a fixed resistor. Variable resistance is called a potentiometer or variable resistor. The ideal resistor is linear, that is, the instantaneous current through the resistor is proportional to the applied instantaneous voltage. Variable resistor for voltage division. On the exposed resistor body, one or two movable metal contacts are pressed tightly. The position of the contact determines the resistance between either end of the resistor and the contact.
The terminal voltage and current have a definite function relationship, and the two-terminal device that reflects the ability of electrical energy to be converted into other forms is represented by the letter R in ohms. Actual devices such as light bulbs, heating wires, resistors, etc. can be represented as resistor elements.
