Resistance current and voltage!

  • #1
I was wondering what the difference in current would be in one full extension cord versus several extension cords (which equal the same length as the first) attatched together?

I was thinking there would be more resistance when the current goes from one cord to another but I'm not sure

There is a very tiny amount of contact resistance (assuming well-maintained cords of the proper rating), but the difference is so small as to have no practical importance.
