Next, ask yourself if electricity is a form of energy. If it's energy, then electricity is not the movable charges. Instead, electricity is made of invisible electromagnetic fields, and it doesn't wiggle back and forth within the AC cables. Instead it can only exist in the space outside the wires, and not within the metal.
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.
Cardinals also drink maple sap from holes made by sapsuckers. Size and Color: Cardinals range from 8 to 9 inches long, with a wingspread of 10-1/4 to 12 inches across. The adult male is bright red with a black face and red bill. The adult female is buff-brown with a red tinge to the crest, wings, and tail. Like the male, the face is black and the bill orange. Special Characteristics: Male and female Cardinals both sing.
