If so, then electricity is simply the charges already inside the wires, where a flow of electricity is a flow of charge. And therefore we must say that the electricity sits inside the wires and vibrates back and forth. Generators do not create any, and electricity does not flow forward through the wires.
Despite the variety of colors and patterns, cats come in three basic colors: red, black, and white. Everything else is a variation of red and black. Now, red encompasses what many people call orange, ginger, yellow and marmalade. Another important point is that solid colors can also be diluted.
Tabbies come in many different colors. You can tell what color a tabby is by looking at the color of its stripes and its tail tip. The color of the agouti hairs (the ground color) may vary tremendously from cat to cat, some cats may have a washed out gray ground color and others will have rich orange tones.
