voltage drop

what is formula for voltage drop for applying cable?

Voltage drop is I^2 *R or V^2/R

worst answer

ans:I*R

Hi Moh,
There is no new formula for Cable Voltage Drop.
The formula is same IR=V. Only thing is that you know the Resistance of the cable you are going to apply which is significant only over a big length.

I think that's enough.

ir kkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk

If you want to apply the voltage drop for the cable, first thing you have to know that, length of the cable, area of crossection, and its specific resistance, then you apply in basic formulas such as
R=s*l/a
and voltage drop = I*R
here s= specific resistance
l= length of the cable
a= area of crossection
hope understand
