hi All (first visit "newbie"), My brother and I have a bet. He says the fuse nearest the wall outlet will always blow first in a multi-strand string of christmas tree lights each connected in "series?" with fused plugs all rated to blow at the same amperage connecting each strand to the next. I seem to recall an electronics lecture which dealt with the near instantaneous response of the circuit in general and a side topic on whether they were electrons in one direction or holes in the opposite, (and push in one end or pull at the other). I think it boils down to minor differences in rated versus actual current capacity of each fuse and that any can blow first regardless of proximity to the wall. Who wins the bet?
