Calculating resistance in a wire
WebSkin resistance of the inductor's wire will increase at higher frequencies. Losses in an iron core usually increase with frequency. B-H nonlinearity of core material affect both inductance and resistance. Some bridges allow measurements of either series RL, or parallel RL models. The more common setup is series RL. WebThe specific resistance or conductance of the wire material must be known. Note, the resistance of the specified simple length is calculated. If you want to calculate the total …
