iPad Battery Connection



     The article talked about the voltage of batteries when they are fully charged. Because of last week’s lesson, these terms are much more familiar. The charge of an atom is generally neutral. When an atom looses electrons, it becomes positive. However, when it gains electrons it becomes negative

Fields of charged objects make up voltage. Voltage is the separation of charges. The lithium poylmer batteries are used because they separate the charges for a long period of time.

Voltage and charge combined make up electric potential energy. However, voltage alone is supplied by a battery. In our lemon battery lab, the lemon supplied a voltage. With a current, resistor, and voltage, a simple circuit is made and electric potential energy can be transferred.
