Lightbulb 1 has the lowest  percentage of energy lost as waste : 25%

Further explanation

Given

The input, output, and waste energy of Lightbulb

Required

The lowest  percentage of energy lost as waste.

Solution

Lightbulb 1 :

[tex]\tt \%energy~lost=\dfrac{50}{200}\times 100\%=25\%[/tex]

Lightbulb 2 :

[tex]\tt \%energy~lost=\dfrac{30}{100}\times 100\%=30\%[/tex]

Lightbulb 3:

[tex]\tt \%energy~lost=\dfrac{100}{150}\times 100\%=66.7\%[/tex]

Answer: lightbulb 1: 200 joules in, 50 joules wasted, 150 joules out
