A 116v electric iron draws 6.29 A if current. How much heat is developed per hour

Question

Physics question that I can seem to figure out 

Answer 1

That is the same as the electrical power.

 

P = VI = (116 v)(6.29 A) = 729.64 watts = 729.64 J/s

 

P = 729.64 J/(1/3600 hour) = 2,626,704 J/hour

 

It develops 2,626,704 J of heat each hour.
