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.
This means one of the circuit conductors (called the grounded conductor in the code) is connected to ground at the service. For homes, this conductor is the neutral, but in some 3-phase systems without a neutral, one of the phase conductors is grounded. The other circuit conductors are ungrounded. This solid conductor to ground is why you can get a shock between the hot conductor and the earth, water, etc. There are countries that do not do this because they feel it is unsafe. However, this grounding of the system keeps the voltages stable.
