(A) power = 0.208 kW = 208 watts (B) energy = 6.6 x 10^{9} joules
Explanation: energy consumed per day = 5 kWh (a) find the power consumed in a day 1 day = 24 hours power = \frac{energy}{time} power = \frac{5}{24} power = 0.208 kW = 208 watts
(b) find the energy consumed in a year assuming it is not a leap year and number of days = 365 days 1 year = 365 x 24 x 60 x 60 = 31,536,000 seconds energy = power x time energy = 208 x 31,536,000 energy = 6.6 x 10^{9} joules
