A group of students trace out two equipotential surfaces and an electric field line as shown in figure 1.4-1.
A) Identify the polarity of each terminalB) calculate the electric field for each segment of the electric field line given that the distance between the two digital multi-meter probe tips is 2.0*10^-2 m. C) Determine the potential difference between the two equipotential lines by summing the voltages along the electric field line. Compare this value to the potential difference found by subtracting the voltage of the two equipotential lines.

Can there be a point between two equal negative charges where the electric potential is zero? What about the electric field? How would the electric potential at a distance of 12 cm from a point charge compare to the electrical potential at 48 cm from the charge? Can two equipotential lines cross? Why or why not? The amount of energy stored in a capacitor depends on what factors?

Two parallel plates
Equipotential Lines represent for us on a graph the same thing
Elevation Lines do for us on a map: They represent a line where the
Electric or Gravitational potential is a constant. Maps and voltage
graphs have even spacing between values (1V or 500ft or 100m etc)so
they can be read easier. These potentials were at 3V, 6V, 9V, 12V,
and 15V. In the figure are 5 lines of electric potential drawn from
positive charge at left...

Calculate the average value of the electric field along the straight line between the two parallel line charges by dividing the difference in the magnitude of the voltages at the two parallel lines by the displacement between them. Then take the % difference between your two values for the average electric field between the parallel line charges.
