Energy Efficiency Solution

Follow our step by step solution on how to calculate Energy Efficiency?

FIRST Step Consider the formula

η = \frac{E t}{E a}

Next Step Substitute values of Variables

∴

η = \frac{1.2KJ}{2.3KJ}

Next Step Convert Units

∴

η = \frac{1200J}{2300J}

Next Step Prepare to Evaluate

∴

η = \frac{1200}{2300}

Next Step Evaluate

∴

η = 0.521739130434783

LAST Step Rounding Answer

∴

η = 0.5217
