Questions and Calculations: 1) How do the equipotential lines differ in the patterns they make for different geometries? 2) How does the potential vary with distance when the two straight electrodes are used? Explain what you expect this relationship to be and why. 3) What is the function of the water in the pan? Would it be possible to do this experiment with air in the pan? If so, how would it be different? If not why not? 4) Explain the relationship between contours of constant potential and the electric field direction 5) Why is the electric field a vector quantity while the electric potential is a scalar?

1) For a point charge, equipotentials are spherically symmetric around the charge. For a pair of charges separated by small distance, equipotentials are not spherical, they get stretched a bit like ellipse (but not exactly ellipse). For uniform electric field, equipotentials are plane surfaces.
2) Potential is inversely proportional to the distance between the electrodes.
3) The function of water in the pan is to maintain the temperature.
4) For a constant potential surface, electric field lines are always perpendicular to them.
5) Electric field is electric force per unit charge, and force is a vector quantity, thus field is a vector.
Electric potential is electric potential energy per unit charge, energy is a scalar quantity and thus the potential.
