# How do you interpret/draw out the simplified circuits in Sedra's Microelectronics?

I legitimately do not understand how the simplified drawings in this book are meant to be interpreted. Coming from a basic circuit analysis class which had everything explicitly drawn, I'm having a lot of trouble even interpreting the simplest circuits in this book and can't even get started with solving them.

Where do the arrows go? This notation is briefly addressed in chapter 1 where it says that the arrows are connected together, but that wouldn't make any sense, since I is given a different value in the problem.
