You are a scientist working on increasing the efficiency of appliances to waste less electricity. you are running experiments measuring the input, output, and waste energy from 3 light bulbs. given the data below, determine which model has the lowest percentage of energy lost as waste.
lightbulb 1: 200 joules in, 50 joules wasted, 150 joules out
lightbulb 2: 100 joules in, 30 joules wasted, 70 joules out
lightbulb 3: 150 joules in, 100 joules wasted, 50 joules out
