How do i calculate how much time it takes to heat water?

All I know is the power supplied and the energy required.

Thanks

power= energy/time

Power*time= energy

you know the energy, you know the power, solve for time.

time(in seconds)= energyinjoules/powerinwatts.

so if the energy is 17640000J and the power is 156w it should take 113076 seconds

Thanks alot

If a 12V battery supplies a 13A current how do I work out the Power supplied
