Resistors
A resistor is a current limiting element. When a resistor is connected to a circuit, the resistance of the resistor is fixed, usually with two pins, and it can limit the current passing through the branch it is connected to. A resistor whose resistance cannot be changed is called a fixed resistor, and a resistor whose resistance can be changed is called a potentiometer or a variable resistor. The main physical characteristic of a resistor is that it converts electrical energy into heat energy. It can also be said that it is an energy-consuming element, and internal energy is generated when current passes through it. Resistors usually play the role of voltage division and current division in circuits.

Resistors: Resistors are widely used in electronic circuits and play a very important auxiliary and regulatory role in circuit design. Their main functions include reducing voltage, distributing voltage, and limiting current. Resistors are one of the most commonly used electronic components in electronic circuits. Their basic function is to control the flow of current by providing resistance, thereby achieving circuit protection, regulation, and signal processing.
