Electric Circuits

Circuit

• A closed loop of conductors through which an

  electric current can flow

• A material that allows electrons to flow freely from

  particle to particle

• The flow of an electric charge through an object

  or medium

• The potential energy per unit of charge that an

  object would have at a point in space as the result

  of the object's charge and the charges of other

  objects at other points in space
