Anatomy of a Battery | HowStuffWorks
Anatomy of a Battery - The anatomy of a battery includes a cathode and anode. ... One terminal is marked (+), or positive, while the other is marked (-), or negative. In normal flashlight batteries, like AA, C or D cell, the terminals are located on the ends. On a 9-volt or car battery, however, the terminals are situated next to each other on ...
20.1: Batteries and Simple Circuits
The Electrochemical Cell. An electric cell can be constructed from metals that have different affinities to be dissolved in acid. A simple cell, similar to that originally made by Volta, can be made using zinc and carbon as the "electrodes" (Volta used silver instead of carbon) and a solution of dilute sulfuric acid (the liquid is called the …
