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.
In physics and electrical engineering, a conductor is an object or type of material that allows the flow of electrical current in one or more directions. For people, a wire is an electrical conductor that can carry electricity along its length.In metals such as copper or aluminum, the movable charged particles are electrons.Positive charges may also be mobile, such as the cationic electrolyte (s) of a battery, or the mobile protons of the proton conductor of a fuel cell.n metals such as copper or aluminum, the movable charged particles are electrons.
