I = 100 W/12 V = 8.33 amps. So this system produces the same power, but with half the current. There is an advantage that comes from using less current to make the same amount of power. The resistance in electrical wires consumes power, and the power consumed increases as the current going through the wires increases.
Biology is the study of life and living organisms, from one-celled creatures to the most complex living organism of all â the human being. Biology includes the study of genes and cells that give living things their special characteristics. You may know that the ology suffix means the study of, and the addition of the Greek bios, meaning life, gives us the meaning of biology. Sometimes science isn't as pretty as that sounds (as you know if you've cut open worms or frogs in biology class).
Bio means life or living organism. Mechanics is the original discipline of physics as it applies to forces on matter. For our purposes,biomechanics is defined as the mechanics of the human body, especially the forces of the muscles and gravity on the skeletal structure of the lower extremity.
