Quizplus · Accepted Answer

When the lamp powered by a wheel generator is turned off, there is no energy being consumed, and therefore, more energy is available to propel the cyclist forward, resulting in them coasting farther. Choosing A or B based on wattage does not have a significant impact on the energy available for the cyclist to coast.
