Derivation of self inductance formula in an LC circuit

Click For Summary
SUMMARY

The discussion centers on the derivation and verification of the self-inductance formula in an LC circuit, specifically L = 1/(4π² . f² . C). Participants emphasize measuring resonant frequencies (f) of various coils and the capacitance (C) of the capacitor involved. The conversation highlights the need for a foundational understanding of LC resonance and the relationship between inductance and resonant frequency. The inquiry also seeks to compare experimental values with known inductance to validate the formula's accuracy.

PREREQUISITES
  • Understanding of LC circuits and resonance
  • Familiarity with the self-inductance formula
  • Knowledge of measuring resonant frequencies
  • Basic concepts of capacitance in electrical circuits
NEXT STEPS
  • Research the derivation of the self-inductance formula in detail

  • Explore the relationship between inductance, frequency, and capacitance
  • Investigate practical experiments to validate the self-inductance formula
USEFUL FOR

Electrical engineers, physics students, and hobbyists interested in circuit design and analysis, particularly those focusing on inductance and resonance in LC circuits.

My observation is to verify self inductance formula by measuring the resonant frequencies of different coils in an LC circuit.For this, I am asked to use this formula by my mentor :

L = 1/(4π^2 . f^2 . C)

Here,
f = different resonant frequencies,
C = capacitance of the capacitor in the LC circuit.How can this be derived from the general formula of self inductance of a coil?

Welcome to the PF.

What reading have you been doing about this subject? Can you post some links to websites that discuss LC resonance?

What are you going to compare the experimental value (formula by your mentor)with? Is the inductance already known to you?
