I am extremely confused about what boundary conditions are. One minute ago I was solving easy capacitor questions and the next minute I am being asked boundary condition questions and there is no such section in my textbook on boundary condition. I have some questions below if you could please explain from scratch/beginner level what boundary condition is and what the goal is.

I have some questions below you could use to explain what these conditions areā€¦ I have looked all over google and search various videos and I still cant find any information on them.

The images don't say anything about boundary conditions. Could you be more specific about what you are being asked, and especially what you don't understand about it? – David Z Mar 1 '12 at 18:53
those are questions, images are figures of the question. I dont know what boundary conditions are and how they are used to find the electric field at different regions with dielectrics – user7918 Mar 2 '12 at 4:06
Someone may post an explanation here, but I really think your best bet is to find a textbook or other resource that explains what boundary conditions are. You may need to look in a textbook on differential equations, because that's really where the idea of boundary conditions comes from. – David Z Mar 8 '12 at 20:20
