Electric arc furnace - An electric arc furnace is a system that heats the charged material by means of an electric arc. Arc furnaces range in size from small units of approximately one ton capacity used in foundries for producing cast iron products, up to about 400 ton units used for secondary steelmaking.

Electric inductance - Electric inductance (inductive electric reactance) is the electric reactance to electric current in the change regimes, which is attributed by the electric self-inductivity of the element of an electric circuit and for harmonic conventionally-stationary regimes is equal to the product of this electric inductivity and the angle frequency.

Electric reactance - Electric reactance is the parameter of a passive two-pole electric circuit or its element, which is equal to the square root of the difference of squares of the full and effective electric resistance for an electric current, taken with the sign plus, if the electric current lags behind the voltage in phase, and with the sign minus, if the electric current leads the voltage in phase.

Electric capacitivity - Electric capacitivity is the scalar value for element of a dielectric circuit, in this same number as the part of an electric circuit, which is numerically equal to dielectric conductivity for the electric induction flux or to relation between this electric induction flux (or the equivalent external electric charge) and the difference of the electric potentials on this element.
