Conductors and Equipotential Lines - Fun!! 1. The problem statement, all variables and given/known data Consider the following two conductors. conductor A is grounded so that it has a voltage of 0 V and conductor B is charged up so it has a voltage of +20 V. Draw in the equipotential lines and then draw in the E field lines indicating direction of the E field. Draw lines for every 2 volts. A is shaped like a diamond and B is shaped like a circle. 2. Relevant equations N/a 3. The attempt at a solution I'm a little confused - could someone define exactly what a grounded conductor is? (I can't find a good definition online or in any of my textbooks). Also, the problem says to draw lines for every 2, so am I correct in assuming that A has no field lines but has equipotential lines and that B would have 5 field lines and the standard circular equipotential lines? Also - A is neutral and B is positive. So does B's equipotential field overlap A's or does it just go around it? Thanks in advance!
