SUMMARY

Anderson's bridge is a modification of Maxwell’s L-C bridge, specifically designed for measuring self-inductance with high accuracy across a range from micro-Henries to several Henries. The method relies on known capacitance and resistances, allowing the unknown self-inductance to be calculated using the formula L = C[(R1 + R2)R5 + R2R4]. In practical applications, a headphone can replace the detector in experiments to measure self-inductance effectively.

PREREQUISITES
  • Understanding of Maxwell’s L-C bridge principles
  • Knowledge of electrical components: resistors and capacitors
  • Familiarity with self-inductance measurement techniques
  • Basic laboratory skills for conducting experiments
NEXT STEPS
  • Study the detailed workings of Maxwell’s L-C bridge
  • Learn about the practical applications of Anderson's bridge in laboratory settings
  • Explore the derivation and implications of the formula L = C[(R1 + R2)R5 + R2R4]
  • Investigate alternative methods for measuring self-inductance
USEFUL FOR

Electrical engineering students, laboratory technicians, and researchers focused on inductance measurement and circuit analysis will benefit from this discussion.

It is a modification of Maxwell’s L - C
bridge. In this bridge, double balance is obtained by the variation of resistances only, the
value of capacitance being fixed.
Anderson’s bridge is the most accurate bridge used for the measurement
of self – inductance over a wide range of values, from a few micro-Henries to several
Henries. In this method the unknown self-inductance is measured in terms of known
capacitance and resistances.
go in your EIM lab and take experiment manual in place of DETECTOR you can use HEAD PHONE and then measure its self-inductance...

i give you a brief explanation ...

the inductance of given coil L = C [ ( R1+ R2 ) R5 + R2R4 ] mH (it is formula to obtain unknown inductive resistance )

Where C = Capacity of the standard capacitor ( µ F )
R2,R3,R4 = Known, fixed and non – inductive resistances (KΩ)
R1, R5 = Variable resistances ( KΩ )
see diagram in your book..
