Energy transferred in the form or to the store required for the device's intended purpose.

Energy transferred in the form or to the store needed for the device's intended purpose.

Useful energy transferred: 950 J. Energy dissipated to surroundings: 30 J. Wasted energy = 980 − 950 = 30 J.

Energy transferred in the way required for the intended purpose of a device or process.

Divide useful energy transferred by total energy supplied, not the other way round.

Use the useful energy transferred as the numerator and the total energy supplied as the denominator.
