I posted a question earliera question earlier that helped me to understand Ohms lawOhm's Law and how power is lost to length of wire shedue to resistance. So my original example was a 15a15A, 10ft cable surge protector plugged into a 15a15A 6 foot cable plugged into a extension cord 13A 10ft 13a which then has the appliance’sappliance's cable at 8 ft. The max power this device would need is 110 watts.

We worked out Ohms law: 𝑃=0.922𝐴×0.434Ω=0.367𝑊

I do not understand how the 0.367 W applies to the power needed (110 watts)? Does this mean if the tvTV needs to pull at max and requests 110 watts it will only receive 109.64? This is safe and will it not damage any of the TVs components, I heard under powering is very bad.
