A circuit consisting of two batteries, two identical resistors, and some wires is represented by the circuit diagram below. +12V +4V Construct a graph showing the value of the electric potential (V) at each point around the circuit starting from the negative side of the +12 V battery and moving counter-clockwise around the circuit. Explain how you knew to draw the graph the way you did. Scientific Abilities Can trace the electric potential through a circuit Is able to construct new representations from previous representations Is able to clearly explain their reasoning in words Missing No attempt is made to identify the potential at different points through a circuit No attempt is made to construct a different representation. No verbal explanation is provided. Inadequate The potential described does not match the circuit. The total potential difference across a closed loop is not zero Representations are attempted but use incorrect information or the representation does not agree with the information. used. Explanation is incoherent, incomplete, confusing, or inconsistent with the work shown. Needs Improvement The total potential difference across all closed loops is zero but the potential does not change appropriately across all elements of the circuit Representations are created without mistakes, but there is information missing, i.e. labels, variables. Explanation is slightly unclear, missing some minor information, covers what was done but is missing why it was done. Adequate The change in potential across all elements of the circuit is correct and represented appropriately (such as with a graph). Explanations are given for the changes in potential Representations are constructed with all given (or understood) information and contain no major flaws. Explanation is clear, detailed, and shows physical and conceptual understanding. Explains both what was done and why.
