Voltaic Cells

Voltaic cells, also known as electrochemical cells, generate electricity through chemical reactions. They consist of two different metals or materials called electrodes, immersed in a solution called an electrolyte. These electrodes have different tendencies to gain or lose electrons. When connected through a circuit, electrons flow from the "anode" (where oxidation occurs) to the "cathode" (where reduction occurs), producing electrical energy. This process powers devices like batteries. Essentially, voltaic cells convert chemical energy directly into electrical energy via spontaneous reactions, enabling portable and rechargeable power sources.
