Electric Energy: Calculating the Cost

Unit 4: Electrostatics and Circuits
Lesson 14 of 16

Objective: Given the local generation service charge for electricity, students calculate the cost of operating various appliances and electronic devices.

Big Idea: The cost of using electric energy (in dollars) can be found by multiplying the electricity service charge (in $ per kW hour) by the power rating of the device (in kilowatts) and the time in use (in hours).
