    """Returns electric potential at node ``n``.
    Electric potential at node ``n``.
    Parameters
    ----------
    n : int
        Node number
    Returns
    -------
    float
        Electric potential
    Examples
    --------
    We create a block of solid material, and constrain the
    volt DOF of all its nodes to a uniform value, and then solve.
    Then we can use ``queries.volt`` to get the Electric Potential
    at the first node of the solved model.
