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, they have fundamentally different functions and design purposes in circuits. Understanding these differences is essential for 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 electric 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 its type, length, area, and temperature).diode

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