What Color Is Positive on a Battery
The positive terminal is the electrode at which electrons flow out of the battery to create a current. This electrode is usually made of metal (like zinc, lead, or nickel) that is capable of conducting electricity. On the other hand, the negative terminal is the electrode at which electrons enter the battery to create a current. This electrode is usually made of carbon or metal.
