Errors of Inductance and Ohmic Resistance of the Cylindrical Inductors

The article presents a brief overview of the electrical parameters of cylindrical inductors, on the basis of which the roots for the occurrence of errors in these parameters are identified. An analysis of the formulas for calculating the inductance and ohmic resistance of inductors is given, as a result of which formulas are derived for calculating the relative errors of these parameters. An example of calculating these errors is considered depending on the design parameters of the inductor: the number of turns, the length and diameter of the inductor, the length and diameter of the wire, the material of the wire and the inductor core. A conclusion is made about the degree of influence of these parameters on the error of inductance and ohmic resistance of the inductor.
