4) A graded potential is just the slight difference in charge across the membrane of a cell. If more negatively charged ions like potassium and sodium go across to the interior of the membrane than the inside charge becomes more negative.
Electric potential is actually defined as the NEGATIVE potential function of electric field (not the vector calculus potential function, but its negative), as is any concept of potential in physics, in order that we can think of it as a form of energy. This means that electric field is the negative gradient of electric potential. If you've never heard of the term gradient, all it means is a vector of derivatives of a scalar function of space, each component of which is a derivative of this function relative to the respective direction in the coordinate system.
