Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.

Question

If an electric heater requires 23 A at 110 V,
determine
a. The power it dissipates as heat or other losses.
b. The energy dissipated by the heater in a 24-h
period.
c. The cost of the energy if the power company
charges at the rate 6 cents/kWh.
