Next, ask yourself if electricity is a form of energy. If it's energy, then electricity is not the movable charges.

Cardinal Color: One of the first and most obvious qualities about the cardinal is his color. Cardinal red is so called because it is one of the three primary colors. The primary colors are red, blue and yellow. All other colors are a combination of these three basic colors. That the visual spectrum begins with red hints at the importance of the cardinal, beginning with his powerful visual presence.
One of the most easily identified songbirds, the cardinal reaches a maximum of 8 to 9 inches in size, with males bearing brilliant red plumage, for which the species is also known as redbirds. The name cardinal is derived from the red robes worn by Roman Catholic cardinals.
