im using the software for Troubleshooting Electrical circuits by BNN. studying this to get prepared as electrician. for if you look at the last 2 pictures, you can see that you can still get 0.3 ohms if the black wire is unplugged

if i just measure the resistance btw L and N , the resistance should be zero right, then how can it be 0.3 ohms ?

im measuring the resistance btw the 2 black wires, each bulb has a resistance of 26 ohms, also the fuse has a resistance of 0.3 ohms.

why is the ohmeter showing 26 ohms here? there is virtually no path for the current to flow from the black lead to the red lead.
