ELECTRIC CURRENTS

(source: everyday Physics phenomena, Mac-Graw-Hill)



Suppose a curcuit is formes with a 12V battery as energy source.
we will pretend that an electric current is made of positive charge, each one carrying 1C of charge
and an energy of 12J. The positive charge flow from the positive pole to the negative pole.
In reality, electrons flow from the negative pole to the positive pole.
Their energy is trnasferred into other forms.
