Abstract

An electrical resistor for heating apparatus comprises a least one resistance wire that is shaped according to at least one wave form and defines coils fitted along an extension axis, and at least one insulating support adapted tc carry the coils and extending along the extension axis; the electrical resistor is of such a nature that the wave form defines a varying undulation density.
