True or false?

Alright, I think this guy's claim is TOTAL bs, but please let me know if I am right or wrong...

The lenth of the wire dictates how many amps it can handle. Im not saying its equivalant but a 3 ft run of 8 gaue will handle the same amount of power as a 12ft run of 4 gauge.

huh?!

he is essentially right. the shorter the cable, the more current it can flow safely. also when he says amps he means amperes and not amplifiers...just fyi. there is a chart somewhere that shows what gauge wire you need depending on length and current draw....

Yes its true.

FALSE

J/K I just felt like being different... Tis true

ever wonder how a fuse works? //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif

...i think he means that like a 3 ft 4 gauge wire could contain as much amps as a 6ft 8 gauge?

The more resistance there is, the more heat that will be generated. A longer piece of wire has more surface area to create this friction than a shorter piece, therefore it will generate more heat, which will yield less power handling (current flow).

This is one of the reasons why its usually acceptable to run a 2 or 0awg wire back to a distribution block in your trunk (for example), and then branch off to the amps with short runs of 4 or 8awg. Those shorter runs of smaller gauge wire will/should handle as much current as the longer run of the larger gauge wire.

Think you might have that backwards....
