When a device or object is going through an energy change, some of the energy that is inputted is TRANSFERRED USEFULLY and some is DISSIPATED or wasted.
Efficiency is a ratio of the amount of useful energy that’s given out to the total amount of energy that was originally put in. The equation for this is:
You can also rewrite the equation using power instead of energy to give you:
You can convert efficiency into percentages by multiplying by 100. For this example, this would give:
0.333 x 100 = 33.3%
