In class, we made our own batteries consisting of lemons, pennies, and nails.
Real World Connection:
On the website http://www.apple.com/batteries/, it talks about how the iPad battery works.
iPad batteries are: made of lithium ion, light but give a long life, and not required to be charged fully.
On the graph on the website, the term voltage was something I noticed quickly. In class, we learned that voltage is the electric field surrounding a charged object.
