Plasma is the aqueous portion of the blood, the acellular portion in which the cellular portions are suspended and transported. It also contains electrolytes and substrates from digestion, such as glucose, fatty acids, and proteins. Hormones also are transported in this part of the blood.
In electrical engineering, ground or earth is the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth.trictly speaking, the terms grounding or earthing are meant to refer to an electrical connection to ground/earth. Bonding is the practice of intentionally electrically connecting metallic items not designed to carry electricity.
1 Earthing and Grounding are actually different terms for expressing the same concept. 2  Ground or earth in a mains electrical wiring system is a conductor that provides a low impedance path to the earth to prevent hazardous voltages from appearing on equipment. One of the most misunderstood and confused concept is difference between Bonding, Grounding and Earthing. 2  Bonding is more clear word compare to Grounding and Earthing but there is a micro difference between Grounding and Earhing. 3  Earthing and Grounding are actually different terms for expressing the same concept.
