Asymmetrical grid with sidebar: Our final example is a very popular asymmetrical layout which makes use of a narrow side column, or âsidebarâ. This sidebar is not used for main body copy, but instead holds related text (headings, pull quotes, notes, and so on), graphics, or simply white space.
From Wikiversity. RL Circuit refers to a circuit having combination of resistance(s) and inductor(s). They are commonly used in chokes of luminescent tubes. In an A.C. circuit, inductors helps in reducing voltage, without the loss of energy. Due to the inductive reactance, the higher the AC frequency, the greater the impeadence of the inductor. Under DC conditions, an inductor acts as a static resistance.
What is A/R? The A/R in a relationship that is obtained when dividing the interior area of the turbine where the inner walls are found, through the turbine housing radio from the center to the tongue as the illustration indicates. A/R values are expressed as .35, .47, .68, .84, 1.00, 1.15, etc. A small A/R indicates a small interior volume in the small turbine and a large A/R indicates a greater volume. At a minimum A/R the motor's response is produced at small revolutions per minute but at high revolutions we will not achieve an adacuate caudal.
