2. Cathode: The cathode is the positive electrode in the voltaic cell, where reduction occurs.
3. Electrolyte: The electrolyte is a substance that contains mobile ions and allows the flow of electric current between the anode and cathode. It can be a liquid (e.g., aqueous solutions of acids, bases, or salts), a solid (e.g., a salt bridge), or a gel.
4. Salt Bridge: A salt bridge is a U-shaped tube containing an electrolyte solution that connects the anode and cathode compartments to maintain electrical neutrality in the cell. It allows the flow of ions between the compartments to balance the charges generated by the redox reactions.
5. External Circuit: The external circuit is a wire connecting the anode and cathode outside the cell, allowing the flow of electric current. It consists of the load, which can be a resistor, light bulb, or any electrical device that utilizes the electrical energy produced by the cell.
