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.

Wattage= 1100 W=1.1 kW

Time for which it is operated in April= 2 hrs a day x 30 days= 60 hrs

Total units (kW-hr)= 1.1x60=66 kW-hr

Cost= Per unit cost * No. of units= 5x66= Rs. 330

Solution: E=Power×Time

E=1.1×2×30

E=1.1×60

E=66 Unit

Rate=Unit×Charge

Rate=66×5

Rate=RS 330

Rate of 66 unit electricity is RS 330

1100w*2(hours daily)=2200w per day.

Now for April total days are 30.

So monthly consumption is 2200*30= 66000w/1000w = 66 units.

Now for a unit company charges about 5rs so the monthly bill will be around 66*5=330rs/-
