I'm just a little confused about field lines. I have sketches of equipotentials and I'm supposed to draw the field lines on them. The one I'm looking at is a dipole with a floating electrode in the middle of the positive and neutral charge. The positive is 12V, and the floating point is 6V. After I draw the lines from the 12 to the 6, do I stop? Continue on the other side to the 0? Do I draw the lines all the way through the floating electrode?
