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.
The full wave rectifier circuit consists of two power diodes connected to a single load resistance (RL) with each diode taking it in turn to supply current to the load. When point A of the transformer is positive with respect to point C, diode D1 conducts in the forward direction as indicated by the arrows.
