Question 
how to measure the voltage drop in cables also give 
formulas to calculate.
 Question Submitted By :: Jaiiseelan
I also faced this Question!!     Rank Answer Posted By  
 
  Re: how to measure the voltage drop in cables also give formulas to calculate.
Answer
# 1		 
Voltage Drop For Different Type of Cable Is As Specified By 
The Cable Manufacturer In Terms Of Volt/Amp/Length(meter)
so with the Help of that We can Calculate The Voltage Drop
Practically At Most 10% Voltage Will Be allowed
 
Is This Answer Correct ?    3 Yes 4 No

  Re: how to measure the voltage drop in cables also give formulas to calculate.
Answer
# 2		 
Voltage drop ( % ) =1.732*I * L* (( R *(cosfie) + X*sin 
(fie ))* 100 /( n*v*1000)
                     

where I is load current 
L is length of cable
R - resistance
X - reactance
fie is angle calculated by tan^-1 ( R/Z )
n is number of runs
v is voltage
 
Is This Answer Correct ?    9 Yes 3 No

Answer
# 3		 
In an cable resistance is depending on 
length ,crossectional area, tempreture,


find the specific resistance of the cable:R=RWO*A/L.

THAN FIND THE VOLTAGE DROP .
