ELECTRICAL ENCYCLOPEDIA

RC and RL Circuits Laboratory Exercises http://www.pa.msu.edu   In this lab we study a simple circuit with a resistor and a capacitor from two points of view, one in time and the other in frequency. The viewpoint in time is based on a differential equation. The equation shows that the RC circuit is an approximate integrator or approximate differentiator. The viewpoint in frequency sees the RC circuit as a filter, either low-pass or high-pass. Formula Representations of RL and RC circuits http://web.eecs.utk.edu   (a) A voltage-step forcing function is shown as the source driving a general network. (b) A simple circuit which, although not the exact equivalent of part (a), may be used as its equivalent in many cases. (c) An exact equivalent of part (a). Series RL Circuits http://www.free-ed.net   The impedance of an RL circuit is the total opposition to AC current flow caused by the resistor (R) and the reactance of the inductor (XL).  ...
