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.
Humans also have three types of cones, allowing them to see a broad spectrum of colors, with sensitivity peaks at red, green and blue. While cats may have three types of cones, the number and distribution of each type varies. In behavioral tests, cats don't seem to see the full range of colors that most humans do.
