To deal with this topic, it is important to present a condition where in; both primary and secondary resistance windings are present. To ensure that you are following the correct diagram, vectors which are to be formed for resistive drops are to be kept in a parallel manner. While those vectors that are that has reactive drops are drawn in a perpendicular manner in regards to current vectors.
A minimal portion of this flux will help in winding or connecting, but cannot help in both cases. This set is called leakage flux and resistance associated with the transformer is impeded comparatively.
