Let's say we've got a nice, negatively charged ring around a positively charged center disc. From the side, the field and equipotential lines would look something like this, I think:

Now, I'm struggling to figure out how this would look from the "top". I'm thinking straight, radial field lines which point outwards from the center disc towards the ring and beyond. Conversely, the equipotential lines would just be increasingly larger circles around the center disc.

Am I thinking correctly? Is there an intuitive way of visualizing electric fields?
