An electric power resistor has a stack of a plurality of resistor plates of metal. Each resistor plate has at least one meandering structure which is formed by a plurality of alternately mutually connected transverse webs. Resistor plates following one another in the stack direction are rotated by 90&#xb0; with respect to one another.

Electrical power resistor

The invention relates to a heating device (), for a mobile inhalation unit for the inhalation of active agents, comprising a heating wire (), with two connector ends () for the introduction of electrical energy and a thermal reservoir () for heating air flowing along the thermal reservoir, whereby the thermal reservoir may be heated by means of the heating wire. The heating wire has a temperature coefficient of at least 0.001 K. The invention further relates to an inhalation unit with such a heating device and a method for heating a thermal reservoir on such a heating device.
