Suppose you have a 2 kW electric heater rated for 220 volt operation, which you intend to operate at a reduced power dissipation of 1kW. Calculate the proper amount of voltage you would need to achieve this reduced power dissipation, and explain how you could use an ideal transformer to supply this reduced voltage to the heater.
