Vedclass · Answer

(D) In electrical devices,the heating effect of electric current is often a desired outcome,such as in a water heater,electric heater,or oven,where the primary function is to produce heat. However,in an electric motor,the primary function is to convert electrical energy into mechanical energy. The heat produced in an electric motor is a byproduct of energy loss (due to resistance in the windings,friction,etc.) and is considered undesirable or 'not appreciated' because it reduces the efficiency of the device.

From the listed electrical devices,which releases heat energy that is not appreciated?
