Hii i think this would be your ans...
Many homes have immersion heaters for heating the water and the two examples given here show how the heating effects of immersion heaters can be calculated. The first example uses a 50 W heater, you have probably used one in school and the second is a 3 kW immersion heater heating water for a bath.
Assuming that the all the electrical energy produced is converted to heat energy we can write: Electrical energy input = Heat energy by the object
Hope this helps
