Electric power is the energy per unit of time that electrical energy is converted into another form of energy.

Recall the equations P=IV and V=IR where P is power, I is current, and R is resistance.

Combining these two equations, you can write P=I2R. Describe what this equation can be used for.

How can you calculate the amount of total energy transferred using the above equations?

What is a killowatt hour and why is it used by power companies?
