Aluminum shell resistor is a double terminal electronic component made of resistance data. It has a certain structure and can restrict the passage of current in the circuit. Fixed resistance refers to the resistance that cannot be changed. Resistance variables are called potentiometers or variable resistors. The ideal resistance is linear, that is, the instantaneous current passing through the resistance is directly proportional to the applied instantaneous voltage. Some special resistors, such as thermistors, varistors and sensitive elements, have a nonlinear relationship between voltage and current. Aluminum shell resistor is the most widely used component in electronic circuits. Depending on the value of power and resistance, they are usually different series. Resistance is mainly used to regulate and stabilize the current and voltage in the circuit. They can be used as shunt and voltage divider, and can also be used as circuit matching load.
