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

Answer 1

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.
