A transformer is 80% efficient. If the input power is 100W, the output power is:

Step 1: Convert the efficiency from percentage to a decimal. Efficiency = 80% = 80/100 = 0.80 Step 2: Use the formula for efficiency to calculate the output power. Efficiency = Output PowerInput Power; Output Power = Efficiency × Input Power; Output Power = 0.80 × 100 W; Output Power = 80 W The output power is 80 W. 80 W

Solved: A transformer is 80% efficient. If the input power…

\text{Efficiency} = \frac{\text{Output Power}}{\text{Input Power}}

\text{Output Power} = \text{Efficiency} \times \text{Input Power}

\text{Output Power} = 0.80 \times 100 \text{ W}

\text{Output Power} = 80 \text{ W}

The output power is 80 W.

80 \text{ W}
