WebH=I 2Rt. H=1 2×12×60. H=720J. (c) The heat produced by the heater will become one - fourth because heat produced is directly proportional to the square of the current. (d) … Heat is not to be confused with internal energy or synonymously thermal energy. While intimately connected to heat, they are distinct physical quantities. As a heating technology, Joule heating has a coefficient of performance of 1.0, meaning that every joule of electrical energy supplied produces one joule of heat. In contrast, a heat pump can have a coefficient of more than 1.0 since it moves additional thermal energy from the environment to th…
