The relationship used to find energy transferred in joules, converting time to seconds and power to watts before multiplying.
An energy transfer equation in which time must be in seconds so energy comes out in joules when power is in watts.
Energy transferred over a time interval, so doubling the time doubles the energy transferred for a constant power.
