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.
RL circuit - Series circuit. 1  By viewing the circuit as a voltage divider, we see that the voltage across the inductor is... 2  and the voltage across the resistor is... 3  The current in the circuit is the same everywhere since the circuit is in series... 4  The transfer function to the inductor voltage is.
