Imagine: your friend is getting ready to head out for the day and their phone gives them a low battery charge warning. They only have ten minutes before they must leave. They have several charging cables to choose from, all different lengths--Which one should they choose? Is there an optimal length to charge your phone? How much can you increase the charge on your phone in 10 minutes? Are there any other factors at play? In this activity, you will measure how much your phone’s battery charges in 10 minutes. You will then submit your results to the Argonne Smart Charging Data Form. Your submission will be one data point within a larger experiment tested by students from all over! Your findings will help answer the questions above.
Congratulations
