AQA GCSE · Question 06.4 · Energy
Write down the equation which links energy transferred, power and time.
Write down the equation which links energy transferred, power and time.
How to approach this question
Recall the definition of power. Power is the rate at which energy is transferred. How can you write this as a mathematical equation involving energy, power, and time?
Full Answer
energy transferred = power × time
Power is defined as the rate of energy transfer.
Power = Energy transferred / time
P = E / t
To find the energy transferred, we can rearrange this equation by multiplying both sides by time (t):
Energy transferred = Power × time
E = P × t
Common mistakes
✗ Writing the equation incorrectly, e.g., Power = Energy × time.
✗ Using the wrong symbols if not writing in words, e.g., P = E × V.
