A home uses ten 100-watt lightbulbs for five hours per day. Approximately how many kilowatt-hours of electrical energy are consumed in one year by using the lightbulbs?

A. 365
B. 1,825
C. 5,000
D. 10,500

Answer :

Approximately 1825 kilowatt-hours of electrical energy are consumed in one year by using ten 100-watt lightbulbs for five hours per day.

To calculate the kilowatt-hours of electrical energy consumed in one year by using ten 100-watt light bulbs for five hours per day, we need to first calculate the total watt-hours consumed in one day and then multiply it by 365 (days in a year).

Total wattage of ten 100-watt light bulbs = 10 x 100 = 1000 watts
Watt-hours consumed in one day = 1000 watts x 5 hours = 5000 watt-hours
Kilowatt-hours consumed in one day = 5000 watt-hours / 1000 = 5 kWh
Kilowatt-hours consumed in one year = 5 kWh x 365 = 1825 kWh

Therefore, approximately 1825 kilowatt-hours of electrical energy are consumed in one year by using ten 100-watt lightbulbs for five hours per day.
