Balancing of bridge is achieved when there is no current through the detector. The maxwell inductor capacitance bridge requires a variable capacitor which is very expensive.

It is seen that the circuit of the maxwell bridge is simply a repeat of the series resistance capacitance bridge with the capacitors replaced by the inductors.

Maxwell induction capacitance bridge. Maxwells inductance bridge measures the value of given inductance by comparison with a variable standard self inductance. As shown in figure 1 in the two arms there are two pure resistances so that for balance relations the phase balance depends on the remaining two arms. A maxwell bridge uses the null deflection method also known as the bridge method to calculate an unknown inductance in a circuit.

Maxwells inductance capacitance bridge in this maxwell bridge the unknown inductor is measured by the standard variable capacitor. Therefore sometimes a fixed standard capacitor is used either because a variable capacitor is not available or because fixed capacitors have a higher degree of accuracy and are less expensive than the various ones. Maxwells inductance bridge the bridge circuit is used for medium inductance and can be arranged to yield results of considerable precision.

Maxwell bridge is used for the measurement of self inductance. Circuit of this bridge is given below inductor capacitance bridge width726 height634 classsize full wp image 7011 maxwells inductance capacitance bridge. A maxwell inductance capacitance bridge known as a maxwell bridge is a modified version of a wheatstone bridge which is used to measure the self inductance of a circuit.

This bridge requires a variable standard capacitor which may be very expensive if calibrated to the high degree of accuracy. When the calibrated components are a parallel resistor and capacitor the bridge is known as a maxwell wien bridge. For measurement of inductance the maxwell bridge shown in figure 1 can be employed.

Like other bridge this method also works on balancing of bridge. Thus sometimes the standard variable capacitor is used in the bridges. Disadvantages of maxwells inductance capacitance bridge.

The circuit diagram of maxwells inductance bridge is shown in figure below. A maxwell bridge is a modification to a wheatstone bridge used to measure an unknown inductance usually of low q value in terms of calibrated resistance and inductance or resistance and capacitance. The bridge is only used for the measurement of medium quality coils.
