How do you find out how much energy is used by an electric heating element?

The heating element is connected to a 110V circut and a current of 3.2A flows through it. How much energy would be used in 5 hours?

Your help is appreciated

P = V*I

P = 110V * 3.2A = 352Volt*ampere = 352 Watts

5 hours = 18000 seconds
18000seconds*352joules/second= 6336 Kilojoule

So in 5 hours we have 6336 Kilojoules
