Inducatnce and Capacitance calculation for rectangular spiral coil

Click For Summary

Discussion Overview

The discussion revolves around finding a formula to calculate the self-inductance and capacitance of a rectangular spiral coil. Participants share resources and seek clarification on the units used in these calculations.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant requests a formula for self-inductance and capacitance specific to rectangular spiral coils, noting the availability of formulas for helical and circular coils.
  • Another participant suggests two external resources that may contain relevant information for calculating inductance and capacitance.
  • A participant expresses difficulty with the provided resources, specifically regarding the units used in the calculations.
  • There is a suggestion that the units might be in micrometers, with a follow-up indicating that one of the resources confirms this unit.
  • A participant speculates that the inductance is measured in microhenries but mentions receiving unexpected values for capacitance and has reached out to the resource provider for clarification.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the appropriate units for the calculations, and there is uncertainty regarding the values obtained for capacitance.

Contextual Notes

Limitations include unclear definitions of units and unresolved discrepancies in calculated values for capacitance.

Hi,

I am looking for a formula that calculates self inductance and capacitance of rectangular spiral coil, i came across many formulas for helical coil and circular spiral coil but couldn't find one for rectangular coil, any help is highly appreciated.

Thanks

Thanks for your help, i tried this one but the problem is, it does not mention the unit in which its calculated.
 
Seems to be micrometers.

I just added a second site which does show it as micrometers.
 
its inductance, so i guess it to be microhenry, but the thing is that it gives me weird value for capacitance when i calculated. i have already mailed circuitdk admin about the information for unit, anyways thanks from your side, if you could find unit let me know so that i can resume my work.

Thanks
