What Is a Resistance Box?

A Resistance Box is a laboratory instrument used to introduce known resistance values into an electrical circuit. By selecting different resistance combinations using removable plugs, users can obtain precise resistance values for electrical experiments and measurements.

The 100 Ohms Resistance Box is widely used in educational laboratories where accurate resistance values are required for practical experiments.

Working Principle

The Resistance Box operates by connecting precision resistance coils in series.

Each resistance coil is connected through brass terminals and removable plugs. By removing or inserting plugs, different resistance values are introduced into the circuit, allowing accurate control of total resistance.

This enables students and researchers to perform precise electrical measurements with ease.
