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. The scientist's definition : Electricity means only one thing: quantities of electricity are measured in Coulombs, so electricity is the electrons and protons themselves; the electric charge inside the wires, and not the flow. Examples: CURRENT OF ELECTRICITY. QUANTITY OF ELECTRICITY. COULOMBS OF ELECTRICITY.
