Question

5. Have you ever noticed that how much electrical energy is consumed by electrical
appliances in your home. Make a chart of all of these appliances with their power in kW
and an average use on daily, weekly, and monthly basis. Usually the electrical power is
written on most of the appliances or on their packing. Calculate the total consumption of
electrical energy in kWh in your home for December, 2020. Find the expected electricity
bill for this month, if 1 kWh energy costs Rs 10. Which item consumed most energy
during the month?

Answer 1

Answer:

Power consumed by a 800 watts microwave in 1 hour = 24 kWh of electricity.

Power consumed by a 500 to 1500 watts A/C in 1 day = 48 kWh.

Power consumed by a 100 and 250 watts fridge in 1 day = 1 to 2 kWh.

Power consumed by an average 10-litre geyser in 1 hour = 2 kWh

Power consumed by an oven in 1 hour = 2.3 kWh.
