You have to use this activity sheet to write down the results from your battery recharge experiment. You will measure power, energy, voltage and current during the recharge of your mobile phone with an USB meter.
* This activity is easy to perform with a regular charger (for example, a standard USB charger or an USB computer port).
* If quick chargers are used, the current, voltage and power will fluctuate greatly due to the charge algorithms. In this case, you might use averaged values although the tables were tougher to fill in.
The class meters will be managed and centraliced by a cadet designated by your teacher. After finishing the battery recharge experiment, this sheet should be filled and handed-in to the teacher
