text: Electrical resistance (usually described as a material's opposition to the flow of an electric current) is used to convert electric energy into thermal energy as an electric current (I) conducted through a material with resistance (R) releases power (P) equal to P = I2R, where P is the power measured in watts, I is the current measured in amperes and R is the resistance measured in ohms.
