A resistor with fixed resistance value is called a

A resistor with a fixed resistance value is called a standard resistor. A standard resistor is an electrical component that provides a precise amount of resistance to an electrical circuit. The resistance value of a standard resistor is determined by its physical properties, such as its length, cross-sectional area, and the type of material used to make it. Standard resistors are often used in electrical and electronic circuits as a reference or comparison standard for measuring other resistors or components. They are also used in voltage divider circuits and as current-limiting resistors. Resistance box, shunt resistor, and multiplier resistor are different types of resistors with specific functions. A resistance box is a device that contains multiple resistors that can be connected in different combinations to produce a specific resistance value. A shunt resistor is used to measure current in high-current circuits by providing a low-resistance path for the current to flow. A multiplier resistor is used in conjunction with other components to increase the output voltage of a circuit.
