What math is involved to determine how many smaller wires equal a larger wire?

[rukiddingme]

For example how many #24 wires equals a #19 wire?


Thanks in advance.

Are you thinking of current carrying capacity?

Patrick's first appendix shoud assist:

If you are talking about area, then the area of the cross section is pi times radius squared
(You will get the radius or diameter from Patrick's tables).

Okay.


So the area of a #24 wire is .205 mm2 and the area of a #17 wire id 1.04 mm2.


That would indicate that it would take 5 #24 wires to make the equivalent of a #17 wire.


Does that sound right to you?


Thanks, I appreciate it.

Paul-R. your answer poses a question I don't know the answer to.


Does a number of smaller wires carry the same current as a larger wire of the same area?

Does a number of smaller wires carry the same current as a larger wire of the same area?

did you mean  ?

"Does a number of smaller wires carry the same current as a larger wire of the same  VOLUME  "
