Question

a) five electric bulbs of 100W each are used for 8 hours daily. 3 fans of 60W each are used for 4 hours daily, a refrigerator of 200W is used for 24 hours. calculate electricity consumed for the month of November.
b) if the rate of electricity is 5per unit, calculate the bill for the month.​

Answer 1

Answer:

A).

Electrical energy by 5 of hundered watt bublb for a day = 5 × 100 × 8 = 4000 Wh.

Electrical energy Consumed by 3 fan of 60 watt for a day = 3 × 60 × 4 = 720 Wh

Electrical energy consumed by a refrigerator of 2000W for a day = 48000Wh

So, Total energy consumed in1 day = 4000 + 720 + 48000 = 52720Wh

Since November month have 30 days so Energy consumed in November Month = 30 × 52,720 =1581600Wh = 1581.6 KWh

B).

Rate = 5rs.

So Bill = 1581.6 × 5 = Rs.7908

Answer 2

Answer:

Rs 7908 is the answer.(approx)
