Physics Question: Work/Energy/Power-related?
An oven operates on a 15.0A current from a 120V source. How much energy will it consume in 3 hours of operation? Please show your work. Thanks a bunch in advance.

You can show the work.
Power in watts is energy / sec
So energy = power * time
and power = v *i
hence energy = V * I * 3 * 3600 ( don't forget that time must be in seconds)
