[RE-wrenches] voltag drop

[Wind-sun.com]

Depends on what table or calculations you are using.

The current has to flow the full distance, out and back, but most tables I have seen have that figured into it. If you are using the resistance from something like AWG wire tables, then you need to use the round trip distance.

  I feel kinda foolish in asking this.....but when calculating voltage drop in a conductor over distance, do I use the one-way or round-trip distance?

  thanks,
