<p>In <a href="page.php?w=electrical_engineering">electrical engineering</a>, an <b>equivalent circuit</b> refers to a theoretical <a href="page.php?w=electrical_network">circuit</a> that retains all of the electrical characteristics of a given circuit. Often, an equivalent circuit is sought that simplifies calculation, and more broadly, that is a simplest form of a more complex circuit in order to aid <a href="page.php?w=Network_analysis_%28electrical_circuits%29">analysis</a>. In its most common form, an equivalent circuit is made up of linear,</p><p>
