The flow of current is also said to have a certain direction; that is, it is noticed that many of its effects are reversed when the terminals of the battery are reversed. Referring to Fig. L, which shows a battery of three cells, the current flows from the copper element at bottom of jar 1, along the wire to the zinc element at top of jar 2, thence through the liquid to the copper element at bottom of jar 2, and from there to the zinc at top of jar 3, etc, and finally through the wire a back to the starting point. Within the battery the current flows from the zinc to the copper and the decomposition of the zinc gen crates the current. In the wire outside of the battery the cur. Rent flows from the copper to the zinc as indicated by arrows. The combination of battery and wire is known as an electric circuit. The current will flow in this circuit only while it is complete, that is while each wire connects to its proper place as shown. If any wire is disconnected, the current flow will cease. Such a circuit is said to be open, but when all connections are properly made it is said to be closed.
