Experimentation with Maxwell’s Bridge

Maxwell’s Bridge trainer is a useful training product for measuring very small values of inductance. It is useful for students to understand the concept and operation of A.C. Bridges. Maxwell’s bridge can be used to determine value of unknown inductance by comparison with either variable standard self-inductance or standard variable capacitance. By setting the null point we can evaluate the unknown inductance value. This product has an on board null detection circuit with differential amplifier, AC to DC convertor and DPM. A 1 KHz sine wave generator is provided with amplitude variation facility.
