How an AI quiz generator helps you study

Multiple-choice, true/false and short answer formats
Explanations for every question, right or wrong
Questions drawn from your own PDFs, slides and notes
Exports to PDF or DOCX on Plus, and QTI 2.1 or Moodle XML on Pro

Example quiz questions on renewable energy sources

Which renewable source generates electricity from sunlight using photovoltaic cells?Solar power. Photovoltaic cells convert light directly into electrical current without a spinning turbine.

True or false: Wind turbines produce electricity only when the wind blows above a minimum speed.True. Turbines need a cut-in wind speed before they start generating, and they shut down above a cut-out speed for safety.

What does the capacity factor of a power plant measure?Actual energy produced over a period divided by the maximum it could produce. It shows how much of its rated power a plant really delivers.

Why is hydropower considered renewable?Water is replenished by the water cycle, so the source is not used up as it generates electricity.

What is geothermal energy?Heat drawn from beneath the Earth's surface to make steam or warm buildings. It is renewable because the planet keeps producing this heat from its interior.
