Test Preparation

In this lesson I've discussed introduction of bridge circuit. Why we use bridge circuita.And discuss what parameters are measured by AC bridge and what parameters are measured by DC bridge.

Introduction of Bridge Circuits

In this lesson I've discussed condition of balancing, Different type of Detectors used in Bridges & Wagner Earth Connection that is used to eliminate the effect of stray capacitance.

Detectors & Wagner Earth Connection

In this lesson I've discussed Quality Factor and Dissipation Factor and also discussed Maxwell's Inductance Bridge that is used to measure Inductance in a coil.

Quality Factor & Dissipation Factor And Maxwell's Inductance Bridge

In this lesson I have discussed Maxwell's Inductance Capcitance Bridge that is used to measure inductance, internal resistance and quality factor of the coil and this Bridge is used to measure mid range quality factor that is between 1 to 10.

Maxwell's Inductance Capcitance Bridge

In this lecture I've discussed Hay's Bridge in detail. Basically Hay's Bridge is used to measure higher quality factor that is greater than 10. In Hay's Bridge balancing is difficult and it's depends on frequency.

Hay's Bridge

In this lecture I've discussed Anderson's Bridge which is used to measure Inductance, internal resistance and quality factor of the coil. And it is used to measure low value of quality factor that is Q < 1. Anderson's Bridge is more complex bridge compare to other AC bridge.

Anderson's Bridge

In this lesson I've discussed Owen's Bridge which is used to measure internal resistance and inductance of the coil. But basically Owen's Bridge is used to measure Relative Permeability.

Owen's Bridge

In this lesson I've discussed Desauty Bridge that is used to measure capacitance and Dissipation Factor of pure and impure capacitor.

De-Sauty Bridge

In this lesson I've discussed Schering Bridge. There are a lot of applications of Schering Bridge like it is used to measure unknown capacitance, thickness of dielectric sheet, permittivity of dielectric sheet, capacitance of underground cable, healthiness of insulators used in power system, healthiness of bushing used in transformer and dissipation factor. And in this lesson I've discussed it's unknown capacitance and dissipation factor application in detail.

Schering Bridge

In this lesson I have discussed measurement of relative permittivity using schering Bridge.

Measurement of Relative Permittivity using Schering Bridge

In this lesson I have discussed Wein's Bridge that is used to measure frequency in MHz range.

Wein's Bridge

In this lesson I have discussed summary of this course and previous year Gate problems based on AC Bridges
