Today the car wouldn't start at a friend's house who had no jumper cables.
He had some electrical wire though.
We were just starting to jury rig something when his wife showed up with
cables in her trunk.

If we did jury rig electrical wires, we were unsure of what size would
work.

How can we determine what size electrical wire would work to jump a
typical
sedan in an emergency?

There is no real way to do that

Sure there is moron, just apply Ohms Law and consult a wire gauge table.
An even simpler way is to just look at some jumper cables and select
a similar wire size. More problematic is how to connect that wire to
the batteries, ie people typically don't have giant size alligator
clamps or similar laying around.




and the quite minimal wire that some
power bank starters is no real indication

He said jumper cables moron.
