Draw the equipotential and electric field line patterns for the following configurations:

1. A parallel plate capacitor

2. A parallel plate capacitor with a small, non-conducting cube placed between the two plates. (i.e. The cube does not take up the entire space between the plates)

3. A parallel plate capacitor but with one of the plates replaced by a circular conductor.

4. A parallel plate capacitor but with one of the plates replaced by an irregularly shaped (pointed) conductor. Why would high voltage engineers avoid using pointed conductors?
