How Do Zinc & Magnesium Oxide Make Electricity?
The Basics All batteries are essentially electrochemical devices. They use the chemical reactions of two different substances to create an electric current. Fundamental battery design needs two electrodes: an anode (negative terminal) and a cathode (positive terminal). These are not placed into direct contact, as doing so would result in a short circuit. They are instead connected indirectly through an electrolyte medium. Using the electrolyte as a bridge, the anode and cathode react so that positively charged electrons travel to the cathode and negatively charged electrons travel to the anode. Standing alone, this operates as a closed circuit for electric current. When a device is connected to the battery, it forms a larger circuit, with power flowing out of the cathode and then back into the anode, minus much of the charge. Zinc-Manganese Most of the batteries used for portable electronics, such as portable radios and iPod players, remote controls and clocks are run on what are calle
