power = work / time

this means power = force * displacement / time

in electricity this equates to P = IV

When in doubt with this sort of stuff type "power equation" into google images it usually throws out a few gems :)

Power = (work done) / (time to do the work)

Power = (energy moved) / (time to move the energy)

Power = (voltage) x (current)

Power = (voltage)² / (resistance)

Power = (current)² x (resistance)
