a) When she went away for the weekend, Celia left her TV on by mistake. The TV has a power rating of 200.0 W. She was away from 6 p.m. on Friday night until 9 p.m. on Sunday. How much energy did leaving the TV on use? Give your answer in kWh. b) If electricity costs 11.3 ¢per kWh, find out how much leaving the TV on costs her. I attached my answer below. I am just wondering if the time is 51h becasue it is 6:00pm on Friday to 9:00pm on Sunday or if it is 3h. My Answer: a) P=200.0W/1000kW=0.2kW Δt=51h ΔE= ? ΔE=PΔt =(0.2kW)(51h) =10.2kWh Therefore, leaving the TV on used 10.2kWh of energy. b) ΔE=10.2kWh rate=11.3¢/kWh Cost= ? Cost=(ΔE)(rate) =(10.2kWh)(11.3¢/kWh) =115.26¢ =$1.15 Therefore, leaving the TV on cost $1.15.
