Electric Potential

Electric potential is the electric charge between two points in a circuit.  Electric potential is seen in our every day life in things like metal door handles or door knobs.  The reason I say this is because a door handle contains a lot of electricity and is charged.  Therefore when someone touches it, the charges are transferred and the person feels a small shock.

 In the picture above, this individual could have been shocked due to the electric potential that is stored inside of the door handle.  The charge in this particular system is present between the door handle and the person.
