The Schering bridge is a type of AC bridge used to measure the value of unknown capacitance.
It is especially useful for measuring small capacitance values and the dielectric loss of capacitors.
It compares the unknown capacitor with a known standard capacitor using balance conditions in the bridge.
Unlike other bridges like Maxwell’s (for inductance) or Kelvin’s (for low resistance), Schering bridge is uniquely suited for capacitive elements.
