Answer:
So, total cost is 210 cents
Explanation:
Given that
Power of Air Conditioner = 2100W
Energy Consumed by in 1 hour = 2100 x 3600s = 7560000
Energy Consumed in Kw-hour in 1 hour = 7560000/3600000
Energy Consumed in Kw-hour in 1 hour = 2.1
Total Running time of Air Conditioner = 10 hours
Cost of per KW- Hour of Air Conditioner = 10 cents
Total Running Cost = ?
As we know
Total Energy Consumed = Total Energy Consumed in 1 hour x Total Running Time
So,
Total Energy Consumed = 2.1 x 10 = 21 KW-hour
Total Cost = Total Energy Consumed x Cost per KW-hour
Total Cost = 21 x 10 = 210 cents
So, total cost is 210 cents
