A television (65w) a refrigerator ( 1.2kw) an electric kettle(650w) and ten lamps (40w) each are connected in series. How much will it cist the house keepers to switch on all the appliances fir 12hrs daily in the month of june if the cost of electricity is N5.00 per unit
First, we need to calculate the total power consumption of the appliances in series:
Total power = TV + fridge + kettle + 10 lamps
Total power = 65W + 1200W + 650W + (10 x 40W)
Total power = 65W + 1200W + 650W + 400W
Total power = 2315W
Next, we need to calculate the energy consumption in kilowatt hours (kWh) per day:
Energy consumption per day = (Total power x time used) / 1000
Energy consumption per day = (2315W x 12 hours) / 1000
Energy consumption per day = 27.78 kWh
Finally, we can calculate the total cost for the month of June:
Total cost = Energy consumption per day x number of days in June x cost per unit
Total cost = 27.78 kWh x 30 days x N5.00 per unit
Total cost = N4167.00
Therefore, it will cost the housekeepers N4167.00 to switch on all the appliances for 12 hours daily in the month of June.
To find out the cost of running all the appliances for 12 hours daily in the month of June, we need to calculate the total power consumption and then multiply it by the cost per unit.
First, calculate the total power consumption in watts:
Total power consumption = Television + Refrigerator + Electric kettle + (Lamps x number of lamps)
Total power consumption = 65W + 1.2kW + 650W + (40W x 10)
Total power consumption = 65W + 1200W + 650W + 400W
Total power consumption = 2315W
Next, calculate the power consumption in kilowatts (kW):
Power consumption in kW = Total power consumption / 1000
Power consumption in kW = 2315W / 1000
Power consumption in kW = 2.315kW
Now, calculate the total energy consumption in kilowatt-hours (kWh) per day:
Energy consumption per day = Power consumption in kW x Number of hours used
Energy consumption per day = 2.315kW x 12 hours
Energy consumption per day = 27.78kWh
Finally, calculate the total cost for the month of June:
Total cost = Energy consumption per day x Number of days in June x Cost per unit
Total cost = 27.78kWh x 30 days x N5.00 per unit
Total cost = 833.4kWh x N5.00
Total cost = N4167.00
Therefore, it will cost the housekeepers N4167.00 to switch on all the appliances for 12 hours daily in the month of June, assuming the cost of electricity is N5.00 per unit.
