Not in Photoshop. You expect functionality which is common in electric circuit diagram editors, flowcharters and presentation graphics programs. It's also in some general purpose vector drawing programs such as Inkscape for easy flowchart, organization diagram, mindmap etc... creation and editing. But Illustrator doesn't have it.
The functionality I mean is a possibility to draw connection lines and curves between objects and keep their ends glued at wanted "connection" or "glue" points (the names vary) when the lines or objects are moved.
The easy to use software with this capability is Microsoft Powerpoint or its free counterparts like drawing programs in Open Office or Libre Office. Inkscape is also free, but its wider possibilities make it more complex. Something in the middle of office programs and general purpose vector drawing programs are flowcharters ans business graphics tools such as such as Microsoft Visio. I got accidentally an ancient Visio version for few bucks.
You seemingly want to include photos and your own symbols, because office programs generally have no electronic component symbols. No problem. You can draw say your battery as a group of lines, grouping keep it together. Photos do not have connection points where the connectors are in the image, but you can insert them as much as you need. I have tested it in Libre Office:
A word of warning:
Connection lines have their own will which can drive you crazy. Have say 50 of them in an office program where you try to put together a circuit diagram. If the parts need to be reordered you will do much better by redrawing the wires than by trying to clean the spaghetti that the program automatically generated when you moved the parts. Flowchart programs and circuit diagram editors can have more intelligence to keep the result easy to read. Electric engineering CAD programs contain much of it.
After practicing drawing a while you may notice the same as me: It's not especially difficult to redraw a wire with the pen, it needs only clicks.
