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.
A LR Series Circuit consists basically of an inductor of inductance L connected in series with a resistor of resistance R. The resistance R is the DC resistive value of the wire turns or loops that goes into making up the inductors coil. Consider the LR series circuit below.
