Ac Bridges. Ac bridges are the circuits that are used for the measurement of electrical quantities such as inductance capacitance resistance. Schering bridge is an ac bridge having four arms which are connected in the form of a rhombus or square shape whose one arm consists of a single resistor one arm consists of a series combination of resistor and capacitor one arm consists of a single capacitor the other arm consists of a parallel combination of resistor and capacitor.
The ac bridges are very convenient and give the accurate result of the measurement. In ac bridges all four arms contain an impedance. The arms of the bridge consist the impedance.

Now let us discuss about these two ac bridges one by one. The ac bridge is constructed by replacing the battery with the ac source. Source and galvanometer with head phone null detector. In ac bridges all four arms contain an impedance.
