Resistance Box

A Resistance Box is an electrical device used to provide a precise and adjustable resistance in an electric circuit. It is commonly used in laboratories and educational settings for experiments involving Ohm’s law, circuit analysis, and calibration of instruments. Key features of a Resistance Box: Contains a set of resistors arranged in a box with selectable values. Resistance values can be adjusted by turning dials or switches. Provides accurate and known resistance values for testing and calibration. Used to vary resistance in circuits without physically changing components. Helps in studying the relationship between voltage, current, and resistance. Typically marked with resistance values in ohms (Ω).
