to the actual electrical resistance to a direct current, being the ratio of electromotive force to the current. It is equal to R2 + X2, where R = ohmic resistance, X = reactance. For an inductive circuit, X = 2pfL, where f = frequency and L = self-inductance; for a circuit with capacity X = 1 ÷ 2pfC, where C = capacity…
