Voltaic Cells
What is Voltaic Cells?
A voltaic cell (galvanic cell) is an electrochemical cell that converts chemical energy from a spontaneous redox reaction into electrical energy. It consists of two half-cells: an anode (oxidation) and a cathode (reduction) connected by an external circuit for electron flow and a salt bridge or porous partition for ion flow. Examples include the Daniell cell (Zn|ZnSO₄||CuSO₄|Cu) and the standard hydrogen electrode; voltaic cells are the basis of all batteries.
