In a house, following appliances are working:
4 tube lights of 40W for 8 hrs daily
2 fans of 60W for 10 hrs daily
1 TV of 200W for 8 hrs daily
Answer the following:
(a) Calculate the total energy consumption per day and for a month (month of April)
(b) What will be the units recorded in the meter for a month of 30 days
(c) Find the electricity bill if cost is Rs.5 per unit ?
Please answer as soon as possible tomorrow is my exam..
We have a relation,
E=P x t
Energy consumed by tube lights=(40/1000) x 8=0.32kWh
Energy consumed by fans=(60/1000) x 10=0.60kWh
Energy consumed by T.V=(200/1000) x 8=1.6kWh
Total energy consumed by all the appliances in a day=0.32+0.60+1.6=2.52 kWh
Total energy consumed by all the appliances in a month (april)=2.52 x 30=75.6kWh or 75.6 units
Cost of electricity in a month=75.6 x 5=Rs 378
