What is maxwell bridge?

Maxwell Bridge is a type of bridge circuit used to measure the inductance of an unknown inductor. It was developed by James Clerk Maxwell in 1864. The bridge circuit consists of a capacitor, a variable resistor, a known resistor, and the unknown inductor. By adjusting the variable resistor, the bridge circuit is balanced, and the inductance of the unknown inductor can be calculated based on the known values of the other components. The Maxwell Bridge is also known as the Maxwell Wein Bridge or Wein Bridge. It is used in various applications, including audio engineering, power electronics, and telecommunications.
