what is importance of anderson bridge
Answers
A large number of AC bridges are available and Anderson's Bridge is an AC bridge used to measure self inductance of the coil. It is a modification of Wheatstones Bridge. It enables us to measure the inductance of a coil using capacitor and resistors and does not require repeated balancing of the bridge.
Advantages:
The fixed capacitor is used, whereas other bridges use a variable capacitor.
The bridge is used for accurate determination of inductance in the millimeter range.
This bridge also gives an accurate result for the determination of capacitance in terms of inductance.
The bridge is easy to balance from the convergence point of view compared to Maxwell’s bridge in case of low values of Q.
Applications:
It is used to measure the self-inductance of the coil(L)
To find the value of inductive reactance (XL) of the coil at a specific frequency
