Ac Bridges. The bridges are formed by replacing the dc battery with the ac source and galvanometer with the wheatstone bridge. The bridge uses for measuring the value of unknown resistance inductance and capacitance is known as the ac bridge.
The ac bridge is constructed by replacing the battery with the ac source. Ac bridges are similar to wheatstone bridge in which d c. The arms of the bridge consist the impedance.
Source and galvanometer with head phone null detector.
The ac bridge consists source balanced detector and the four arms. The bridge uses for measuring the value of unknown resistance inductance and capacitance is known as the ac bridge. Ac bridge circuits can be of the symmetrical type where an unknown impedance is balanced by a standard impedance of similar type on the same side top or bottom of the bridge. Ac bridges are the circuits that are used for the measurement of electrical quantities such as inductance capacitance resistance.
