Answer:
The total number of hours=2*30=60
Total energy consumption=60*1,1= 66 kWh
Energy cost = 66*5= Rs 330
It is to be noted that the iron has a thermostat, which trips when the set temperature is reached. The thermostat also resets when the temperature falls. This results in a duty cycle with an “on” period followed by an “off” period. This would result in a substantially lower energy consumption...!
