The similarities could better be related to a hydraulic system. If you were to overlap a hydraulic schematic with a similar electrical diagram, you could find that they are almost identical in the functions of valves/ diodes/ solenoids/ switches/ pressure/ return/ etc. there are many similarities relatable to a hydraulic system and an electrical system. They are not the same. But when using one to learn another it becomes easier for explanation.
For instance, pressure and flow versus voltage and amperage. Unrestriced hose/line means you get max flow low pressure, restrict the line you get less flow and higher pressure. Same goes for electricity. You take voltage through a big wire and you drop it down into a smaller wire not rated to carry similar voltage and poof! Youve let the magic out.

The similarities are just a metaphor to help students understand Ohm's Law.

I'm pretty sure thats what OP meant when he said:
