This week, we learned about voltage and how it is used in our lives, so for homework we had to research more about iPads.
Voltage (electric potential) is defined as a field that surrounds charged objects.
iPad battery:
The battery is an interchangeable, rechargeable lithium-polymer battery. (http://www.apple.com/batteries/ipad.html)
It is also supposed to last 10 hours until it is necessary to charge again. To charge the iPad, a charger with 10 Watts and an output of 5.1 Volts is required.
Nothing has been release about future works on iPads, but sources speculate that it will probably be able to charge faster (energy will be transferred faster), and the new technology doesn't have the ability to overheat the iPad while it is charging, even if energy is being transferred.
