Answer:
The answer is C ) 27.5 W
Explanation:
It means that from the 110 Watts it uses 75% to do its job. Therefore we have:
Pu = Power used = 110 * (75/100) = 82.5 watts
82.5 watts are used for the tv work.
And the difference between the total power and the power used is the power wasted as heat.
(110 - 82.5) = 27.5 watts
27.5 watts are dissipated as heat
