[Problem] To provide a load resistor: which has arranged therein a plurality of resistant rods that generate heat only to about 100° C. or less due to power supply from an emergency power generator, for example, and that rapidly lose the heat by mere exposure to the air; and which, therefore, does not need a cooling device to be installed for forcibly cooling the resistant rods, or a cooling fan that would be extremely heavy, have a large capacity, and end up accounting for about half of the ;eight and about the lower half of the volume constituting the load resistor. [Solution] The present invention is a load resistor that receives power transmitted from an apparatus and performs an energization test on the apparatus. The load resistor is characterized by comprising a rod-shaped resistive base body that is energized with the power and generates heat, a pipe-shaped protective member through which the rod-shaped resistive base body penetrates, and rod-shaped resistors having an insulation member that are packed in between the rod-shaped resistive base body and the protective member, the rod-shaped resistive base body having used therein a stretched nichrome wire that is wound in the shape of a coil.

A power resistor is disclosed, having at least one electrical connection, having a carrier substrate, which has at least one resistor element composed of a thick-film material and at least one contact electrode to which the resistor element electrically connects, having at least one electrical conductor, which is soldered to the contact electrode and produces an electrical connection between the contact electrode and the electrical terminal, and having a housing, which is at least partially filled with at least one casting compound and in which the resistor element and contact electrode are encapsulated, with the electrical conductor protruding out through the casting compound. In order to achieve a simply designed and easy-to-use power resistor, it is proposed for a pin, in particular a soldering pin or press-fitting pin, to constitute the electrical conductor, which pin is placed onto the contact electrode and soldered to it and constitutes the electrical terminal of the power resistor.
