Wirewound Resistor 15 OHM 10% 25W. (Load TU775-2).
A resistor is an electrical component which provides some resistance to the flow of electricity. This resistance determines how much current will flow for a given voltage applied across the resistor. The result of resistance is the production of heat. Incandescent light bulbs are specialized resistors, which gets so hot that they glow, producing light. Resistance is measured in ohms.
