question 26 of 29\na tv has a power of 110 watts and an efficiency of 75 percent. how much power is wasted as heat?\na. 27.5w\nb. 4.4w\nc. 1.5w\nd. 82.5w

Answer

Explanation:

Step1: Calculate the wasted - power percentage

The efficiency is 75%, so the percentage of power wasted is $100% - 75%=25%$.

Step2: Calculate the wasted power

The total power of the TV is 110 watts. The wasted power $P_{wasted}$ is given by $P_{wasted}=0.25\times110$ watts. $P_{wasted}=27.5$ watts.

Answer:

A. 27.5W
