PRE-LAB ASSIGNMENT 1. How are the Electric eld lines drawn? 2.What are the voltages of the points where the potential is the same (in 3-d space)? 3.What is the geometric structure of the points where the potential is the same (in 3-d space)? 4.For this lab why are the measures equipotential lines instead of surfaces? 5.What is the relationship between the direction of the electric field lines and the equipotential surfaces
