PLEASE help with physics!?

A 133 Volt electric iron draws 8.31 Amperes of current.
How much heat is developed per hour? Answer in units of Joules.

all i know is you need to use ohm's law. someone pleeeease help me?

You do not use ohm's law (V = iR) for this problem.

Rather, you are using the definition of power (P = iV)

Power = current (i.e. coulomb's per second) x voltage (i.e. joules per coulomb).

= 133 x 8.31.

The amount of ENERGY is E = Pt = 133 x 8.31 x 3600 (the number of seconds in one hour).
