How Much Heat Does a 111V Electric Iron Develop in One Hour?

[AdnamaLeigh]

A 111 V electric iron draws 8.9 A of current. How much heat is developed per hour? Answer in units of J.

P = IV
P = U/t
U = IVt
U = 8.9(111)(60) = 59274 J

Apparently I'm wrong and I don't know why.

A = (C/s)

You have 60 mins, your units have a missmatch.
