Page 2, Figure 1.1, "parallel connection". See the lack of an EMF in that diagram?
Yes, now see the text directly under the diagram which says, and I quote, "Things hooked in parallel (Figure 1.1) have the same voltage across them.". So no the source of the EMF is not shown but it is clearly there as the text underneath states. Thank you for proving my point.
OKey dokey, since you keep dodging this question I'll ask again.
The line you quoted answers the question you asked: if the current does not divide between two or more paths then the devices are not connected in parallel. Apply that to your situation: if there is a current and it splits to pass through two devices you have a parallel circuit. If not, you do not. It's literally that simple. Apply that simple rule to whatever ideas you come up with and it will tell you if it's connected in parallel. It's not pedantic, it's simple and easy and the definition of a parallel circuit. Switches break circuits and so yes, it should not be a surprise to someone who has Horowitz & Hill on their shelf that they can change whether something is connected in parallel. In fact it's really easy to imagine using switches to convert a parallel circuit to a series circuit.
