Question

an bulb of hundred watts power is used for 10 hours a day calculate the electricity bill to be paid if electricity is charged@ rupees 6/ unit​

Answer 1

Explanation:

Five bulbs consume the power of 100 W each.

The total power consumed by 5 bulbs = 5 x 100 = 500 W = 0.5 kilowatt

Electrical energy consumed daily is, E = P x t = 0.5 kW x 10 hours = 5 kWh.

Thus, total electrical energy consumed for 30 days = 5 kWh x 30 days = 150 kWh or 150 units.

The cost of 1 unit of electricity = Rs. 4

Thus, the total cost of electricity = Rs. 4 x 150 = Rs. 600.

Answer 2

Answer:

1000

So a 100-Watt bulb if kept on for 10 hours will consume: 100 x 10 = 1000 Watt-Hour = 1 Kilowatt-Hour (kWH) = 1 units (on your meter).
