Hi
I watched this video of a guy testing a fusebox with a multimeter:
if you skip to 6:10 he uses a multimeter on a particular fuse and
when putting the black lead on good ground of car and red lead on either side of the fuse he gets the same reading on both sides. He even comments that
there should be the same reading! yet I don't see how:
the fuse must have SOME resistance so when connecting to the end which is furthest from the negative terminal battery won't the reading be slightly less? electron has to travel through the wires to nearest end of the fuse. the eelectron has to lose potential overcoming the resistance in the fuse when it passes through the first end of fuse and reaches the other end. (the one further away) so at that end won't the reading for potential difference/voltage be less?
