Inductive loads use magnetic fields (i.e., wire wound coil), as in a furnace, air conditioning unit, or blender. The general rule is, if it moves, it is probably an inductive load, which pulls a large amount of current (inrush current) when it is first energized. But after a few cycles or seconds, the current settles down to a steady state. This steady state is typically the wattage rating you see on the product label. The peak wattage, which occurs with the inrush current, is normally found in the owner’s manual.

Resistive loads convert current into other forms of energy, such as heat. Hair dryers and heaters typically create resistive loads, characterized by not having large inrush currents. The wattage ratings of resistive loads can be taken at face value and are exactly as indicated on their labels.
