Parallel and series


Figure depicting the equivalent value of series and parallel connected inductors.

    Entering a list of comma separated values (i.e. 320µ, 1.2m, 110u) to find the series and parallel equivalent values.

    Connecting any number of inductors in series or parallel will result in an equivalent inductance. This equivalent inductance can be used in place of a single resistor. Although this is not commonly done (simply purchasing the correct value inductor is less expensive and simpler to deal with) there are some reasons why doing so is advantageous.

    In a high voltage circuit, using a series connected group of inductors distributes the voltage drop and therefore prevents the inductors from breaking down. In some cases, the inductors internal resistance may prove problematic. Placing them in parallel reduce the net resistance of the parallel inductor group. When prototyping and you don’t have the value you need on hand, you can use a series or parallel connecter group to make the value you need.
