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.
Electricians sometimes call the neutral common because at the service entrance, all the neutral wires go to a common buss, whereas each hot leg connects to its own distribution breaker. However the term common actually refers to drawings of electrical circuits.est Answer: In Y or a delta transformer there are four wires. three hot wires and one middle wire called common wire or neutral wire or sometimes it is grounded and called ground.
