In the absence of anything else, the live and neutral wires are exactly the same. Both carry current. You need a circuit, and that means a circle. The two wires form a circle, and in that circle is the power supply (usually a transformer on a pole or in a green case on the street) your load, and probably a switch. The two wires are just the two parts of a circle or loop at any given point.
Reflux is a distillation technique involving the condensation of vapors and the return of this condensate to the system from which it originated.he more reflux provided for a given number of theoretical plates, the better is the column's separation of lower boiling materials from higher boiling materials. Conversely, for a given desired separation, the more reflux is provided, the fewer theoretical plates are required.
Distillation. Distillation is a process that can be used to separate a pure liquid from a mixture of liquids. It works when the liquids have different boiling points. Distillation is commonly used to separate ethanol-the alcohol in alcoholic drinks-from water. Distillation process to separate ethanol from water.
