The dc resistance of a conductor is calculated using the resistivity and the cross-sectional area:- Equation 1. Unfortunately for the size and inductance I need, one layer is insufficient, and the mutual inductance between multiple layers means the equations for single layer planar coils aren't accurate when you simply multiply by the number of layers desired. The coil has an inductance (expressed in Henry and submultiples – “L”), a ballast to the passage of alternating current (expressed in Ohms – “X”), a resistance to the passage of direct current (“R” – in Ohms) , a Electronics Projects, Air Core, Toroid Coil Calculator Programs " electronics software tools, " Date 2019/08/02.
