N newbe_always New Member Oct 11, 2024 #1 I am characterizing a wireless transfer coil with the help of this document from Omicron. In page no no-7 you can see that they are finding the resistance of the coil at resonance and it's value is 9.304K Ohm. May I know the significance or impact of this resistance in wireless power transfer. I believe it has no significance,they are just finding the resonance frequency for other calculations.Please correct me if I am wrong.
