The two galvanic cells both have copper, but the needle points different directions because the copper ions have a higher potential than zinc ions but not higher than the silver ions.

A galvanic cell would be an electrochemical device that uses spontaneously redox reactions that transform chemical energy into electrical energy. It also goes by the name "voltaic cell."

Galvanic cells employ the electrical energy generated by the transport of electrons during a redox reaction to carry out practical electrical work. By separating the oxidation as well as reduction half-reactions as well as connecting them with a wire in which the electrons must pass through the wire, it is possible to gather the electron flow.
