how does it work?? i am really too confused and can't understand its idea.
can anyone help??
can anyone help??
Anderson bridge used to measure self-inductance.
Click For Summary
Discussion Overview
The discussion revolves around the Anderson bridge and its application in measuring self-inductance. Participants express confusion about the working principles of the bridge and seek clarification on its operation and underlying concepts.
Discussion Character
- Exploratory
- Technical explanation
- Homework-related
Main Points Raised
- Some participants express confusion about how the Anderson bridge operates and request assistance in understanding its principles.
- One participant provides a link to a resource that may contribute to the discussion on the topic.
- Another participant explains that the Anderson bridge is a modification of Maxwell’s L-C bridge, emphasizing its accuracy in measuring self-inductance across a wide range of values.
- A formula for calculating the unknown inductance in terms of known capacitance and resistances is presented, along with a suggestion to use headphones as a detector in a laboratory setting.
- Further assistance is offered by one participant, inviting others to ask additional questions.
Areas of Agreement / Disagreement
Participants generally express confusion and seek clarification, indicating a lack of consensus on the understanding of the Anderson bridge's operation.
Contextual Notes
Some assumptions about the familiarity with related concepts, such as Maxwell’s L-C bridge and the specific laboratory setup, may not be universally shared among participants.

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..
