Title: current over a wire
Post by: chrisatpsu on February 08, 2012,

anybody know what kind of current i can get away with over a awg30 solid core wire?
2v
5v
12v

You can get away with about 2 amps (any voltage). It WILL heat the wire at that current and you will see voltage loss over long distances.

so i should be safe for 20mA single led type currents?

obviously with a resistor

Current travels through and voltage carries over .

here is a good reference :)

The actual "power transmission" rating is .142 amps and "signal transmission" rating of .86 amps. If you stay within those two, you should see zero negative effects, even at long distances.

most likely 20mA <1ft @5vdc

This would be a good look for the wiki

why do you need a resistor...



 ;)

i should delete this message before I start getting responses.
for anyone not reading the other thread, resistors are thoroughly discussed here:
