In the seven circuits shown below there are two sets of three identical circuits and one "oddball". Identify the "oddball" and state which of the remaining circuits are electrically equivalent to each other. Explain, using the concept of common points, why the circuits you identify are equivalent. w www ww w-w (1) (2) (3) ww w w www w ww ww w ww w (4) (5) (6) (7) 4. For the following circuits, circle the circuits that can be analyzed by separating them into simple series or parallel combinations. Draw a K on the circuits that must be analyzed using Kirchhoff's rules. K Wh
