The difference between close and open circuit using ohms law

The difference between close and open circuit is that a open circuit means the wire is cut off at some point and this prevents electrons from traveling from one side of the power source to the other and there is no flow. A closed circuit is that the wire is connected and there is a flow but there is no voltage.
