## Voltage Drop for ConEst

Continuing a recent conversation
I've been having with [[joel-jansen]]
on [[voltage-drop]],
both ideally and for application in [[conest|ConEst]],
Joel brought Bill Swan with [[pdi-estimating-solutions|Estimating Solutions]]
over to my desk.
Bill said that when he is calculating voltage drop
he doesn't the ubiquitous "Voltage Drop Calc 2011.xlsx"
which uses a simple DC calculation,
he uses [[pdi-vdc|VDC]]'s calculator,
which is based on AC resistance and reactance.

I showed them my own calculator,
which also has AC capability
The difference
