An electric heater of 1200 W is operated for 3 hrs daily. What will be the electrical consumption expenses for that in the month of June ? (The electric company charges Rs 5 per unit of energy.) Analyse Step 1 : To get the electrical consumption expenses of the month of June, we need to know the energy consumed by the electric heater in that month in terms of units. Step 2 : Key factors to understand : i. To find the expenses, "Electrical consumption expenses "="Energy consumed (in units)"xx"charge per unit " ii. "1 unit "="1 kWh" i.e. in order to find the energy inunit, we need to find it in terms of kWh (kilowatt hour)
