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.
What is Distillation? Distillation is a widely used method for separating the component substances from a liquid mixture by selective evaporation and condensation. To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points, into the gas phase. In industrial chemistry, distillation is a unit operation of practically universal importance, but it is a physical separation process and not a chemical reaction.
