Topic: Voltatic (or Galvanic) Cells

Voltaic (or Galvanic) cells convert chemical energy into electrical energy using a spontaneous redox reaction. The reaction is split into two half-cells: the anode (where oxidation occurs) and the cathode (where reduction occurs). Electrons flow through an external wire from the anode to the cathode, creating current. A salt bridge connects the solutions, allowing ions to flow to maintain electrical neutrality and keep the reaction going.
