How do batteries work? A simple introduction
When a zinc-carbon battery is wired into a circuit, different reactions happen at the two electrodes. At the negative electrode, zinc is converted into zinc ions and electrons, which provide power to the circuit. At the positive electrode, manganese (IV) oxide turns to manganese (III) oxide and ammonia.
