What is the difference between a resistor and a resistor fuse, and can a fuse resistor replace a regular resistor? 1

Although resistors and resistor fuses are similar in name, their functions and design purposes in circuits are fundamentally different. Understanding these differences helps in their proper use in circuit design and troubleshooting. diode

The basic function of a resistor

Resistance is one of the most fundamental components in a circuit, primarily functioning to limit the flow of current. According to Ohm's Law (V = IR), we understand the relationship between voltage (V), current (I), and resistance (R). Resistance controls the magnitude of current by providing a "resistance," which is closely related to the properties of the material (such as the type, length, area, and temperature of the material).diode

Resistors can be used in various circuits, such as voltage divider circuits, AMS1117-3.3 filters, bias circuits, and others. They are indispensable components in circuit design. The selection and application of resistors are based on parameters such as resistance (ohms), power rating (watts), and tolerance.diode
