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 factor of merit.
L ‘inductance is the ability to store electrical energy in an electromagnetic field. The ballast is an electrical resistance element that offers to the passage of an alternating current having a certain frequency. The factor of merit (or quality) expressed with the letter Q is the ratio of the reactance (inductive in this case) and the sum of all the losses associated with the decrease in energy in transit
