Description
The Maxwell Inductance Bridge is a high-accuracy AC bridge apparatus designed to measure the self-inductance of an unknown inductor by comparison with a known standard capacitor and resistive elements. This classical bridge method is widely used in physics and electrical engineering laboratories to study inductance, AC bridge balancing, and frequency-independent measurements.
Ideal for undergraduate and postgraduate physics labs, electrical engineering laboratories, polytechnic institutes, and technical training centers.
