How does a galvanic cell work?

Answer 1

.. A redox reaction at two electrodes causes electrons to flow.

Answer 2

A galvanic cell works by converting chemical energy into electrical energy through redox reactions. As the two half-cells (anode and cathode) are connected by a conducting wire and a salt bridge, electrons flow from the anode to the cathode, causing a potential difference and generating an electric current. The anode undergoes oxidation, releasing electrons, while the cathode undergoes reduction, accepting the electrons.
