ANDERSON BRIDGE | Precision AC Bridge Apparatus for Measurement of Self Inductance

Description

The Anderson Bridge Apparatus is a high-accuracy laboratory instrument designed to determine the self-inductance of a coil using an AC bridge method. An advanced modification of the Maxwell bridge, the Anderson Bridge provides greater accuracy by incorporating a fixed standard capacitor and precise resistance elements.
Ideal for physics laboratories, electrical engineering labs, universities, and polytechnic institutes, this apparatus helps students understand AC bridge networks, inductive reactance, and impedance measurement techniques.
