Question

passage (excerpt): \solar panels convert sunlight into electricity using photovoltaic cells. these cells are made of layers of semiconductor materials that free electrons when struck by photons. the freed electrons flow through a circuit, producing usable current.\ question: which sentence best explains how the author develops the main ideas about how solar panels work? by providing step - by - step explanation of the process from sunlight to electric current. by comparing solar panels to wind turbines. by giving a historical timeline of when solar panels were first invented. a. by describing the emotional benefits of using solar energy. clear my selection

Explanation:

The passage first mentions solar panels use photovoltaic cells, then describes what happens when photons strike (free electrons), and finally how electrons flow to produce current. This is a step - by - step process. There is no comparison to wind turbines (no mention of wind turbines), no historical timeline (no dates about invention), and no emotional benefits (no words about feelings like happiness from using solar energy).

Answer:

By providing step - by - step explanation of the process from sunlight to electric current.
