In this video you will learn all the science for this topic to get a grade 9 or A* in your science exams!
The formula linking power, energy transferred and time is:
power (P) = energy transferred (E) ÷ time (t)
Rearrange for: energy transferred = power x time
Rearrange for: time = energy transferred ÷ power
The unit for power: watts (W)
The unit for energy transferred: joules (J)
The unit for time: seconds (s)
