how to calculate the bus-bar size. give formula with
description
Answer Posted / gulmohammdeibrahim
BUS BAR SIZE PURELY DEPENDS UPON THE VALUE OF CURRENT
use this formula
R=rowl/a
a= area of cross section
now a=rowl/r
r= resistance value
r=v/i
hence
a=row *l*i/v
hnce
a directly proportional to i(Current)]
