Question

Calculate the amount of energy required and energy supplied to fan in the month of December. If fan runs for 4 hours a day with V = 110V , I = 1.2 A Also calculate the electric bill of fan if ( 1 units = 6 ₹)​

Answer 1

Answer:

Energy consumed by 4 tubelights per day, E

tubelight

=(4)(40)(5)=800 WH

Energy consumed by 3 fans per day, E

fan

=(3)(80)(12)=2880 WH

Energy consumed by television per day, E

TV

=(100)(6)=600 WH

Total energy consumed per day, E=E

tubelight

+E

fan

+E

TV

∴ E=800+2880+600=4280 WH =4.280 KWH per day

Total energy consumed in 30 days, E

T

=30×4.280=128.4 KWH

Cost of electric energy =Rs. 3.00×128.4=Rs. 385.20

Answer 2

Answer:

Rs. 385.20

Cost of electric energy =Rs. 3.00×128.4=Rs. 385.2
