The coefficient of performance (COP) for electric resistance heat is defined as?

The coefficient of performance (COP) for electric resistance heat is defined as the ratio of useful heating or cooling provided to the amount of energy consumed. In the case of electric resistance heating, the COP is typically represented as 1 to 1. This means that for every unit of electricity consumed, one unit of heat is produced.

In practical terms, this indicates that an electric resistance heater is perfectly efficient, converting all electrical energy into heat without any losses in conversion efficiency. Hence, when examining the performance metrics of electric resistance heating systems, a COP of 1 clearly reflects this ideal efficiency, making it the appropriate definition in this context.
