I wanted to implement below formula into excel sheet. can someone suggest me with example.
cable equation example : system voltage =12v, sys current=8A, length in feet=50.
Resistance = resistivity* length/ area
length = 50 feet
if we consider 26 gauge wire
diameter of wire =0.0159 inch =0.001325 feet
radius =0.01325/2 =0.006625
a = pi* radius^2= 0.000137090
therefore wire resistance= 0.0060
but data i got is not matching with value in table mention. can you some one suggest what mistake i am doing
wire gauge calculation
I am not saying my answer is correct . If you check the online calculator i posted it gives right choise of wire gauge.
i am trying to impliment same thing in excel sheet.
Help i need is example to explain the choose correct value & get answer similar to the online
length of cable= 50 feet
source voltage =12v
my intension to calculate re
- resistance per length in ohm
- voltage drop
- % voltage drop
- % loss
- select area which is good for the application
