Question

An oven at a 24 hr diner uses 24.7 A of electricity when it operates on a 120 V circuit. If electricity costs $0.080 per kWh, what would it cost to run the stove while cooking food for one day? Assume the oven is on for 24 hrs at the same temperature.

Answer 1

Total cost to run the stove while cooking food for one day = $5.69

Step-by-step explanation:

An oven at a 24 hr diner uses 24.7 A of electricity when it operates on a 120 V circuit.

Power consumed (P) = 24.7 (120) = 2964 W

Hours of use per day = 24

Energy consumed per day =
`(Power (time))/(1000)` =
`(2964 (24))/(1000)` = 71.136 kWh/day

Electricity costs per kWh = $0.080

Total energy costs = 0.08 (71.136) = $5.69

Total cost to run the stove while cooking food for one day = $5.69
