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.
Lesson Summary. Electric potential is the level of power behind a flow of electricity, but shouldn't be confused with the electric current itself. We often refer to electric potential as voltage and measure it in volts (V), which is found by dividing work (joules) by charge (coulomb). The larger the voltage, the stronger the 'push' of electricity, operating much like the water pressure in a shower. To unlock this lesson you must be a Study.com Member.
