Answer

80 W

Step 1: Convert the efficiency from percentage to a decimal. $Efficiency = 80\% = \frac{80}{100} = 0.80$

Step 2: Use the formula for efficiency to calculate the output power. $Efficiency = \frac{Output Power}{Input Power}$ $Output Power = Efficiency \times Input Power$ $Output Power = 0.80 \times 100 W$ $Output Power = 80 W$

The output power is 80 W.

$80 \text{ W}$
