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.
Definition of a Battery. Photo Credit: ose Luis Pelaez/ The Image Bank/ Getty Images. A battery, which is actually an electric cell, is a device that produces electricity from a chemical reaction.Strictly speaking, a battery consists of two or more cells connected in series or parallel, but the term is generally used for a single cell.A cell consists of a negative electrode; an electrolyte, which conducts ions; a separator, also an ion conductor; and a positive electrode.hen the cell is connected to an external load, or device to be powered, the negative electrode supplies a current of electrons that flow through the load and are accepted by the positive electrode. When the external load is removed the reaction ceases.
