The cost of energy delivered to residences by electrical transmission varies from $0.070/kWh to $0.258/kWh throughout the United States; $0.110/kWh is the average value. (a) At this average price, calculate the cost of leaving a 10-W porch light on for two weeks while you are on vacation

The cost of leaving a 10-W porch light on for two weeks while you are on vacation is $0.37

Explanation:

Given:

the average cost of energy delivered = $0.110/kWh

⇒ To calculate the cost of leaving a 10-W porch light on for two weeks while you are on vacation;

⇒convert 10 W to kilowatt (kW) = (10/1000) = 0.01 kW

⇒convert two weeks to hour (h)

Energy rate (kWh) = 0.01*336 = 3.36 kWh

Energy cost = (3.36 kWh)*($0.110/kWh)

Energy cost = $0.37

Therefore,  the cost of leaving a 10-W porch light on for two weeks while you are on vacation is $0.37
