/diy/ - Do It Yourself

Hey /ohm/ I'm a total beginner and have a silly question. Before you ask, no I'm not a student and no this is not my homework. I'm getting into it as a hobby.

I'm struggling to find the nodes and label them, and because of that I am unable to know which resistors are in parallel or in series.

If you have a resource I could learn from I'd be very happy; but I'd be very glad if you could explain it as well.

Could you label the nodes in the image to the left and explain why? Because I don't know when a node starts and ends.
I'd really appreciate it, thank you.
