Answer / iamdon

We can use the fundamental relation amoung
Resistance(R),Resistivity(p),length(l) and cross sectional
area(A) of conductor.
R=(p*l)/A

Being busbar made of Aluminium,its resistivity(p),which is
a property of metal and is independent of dimension,is known
(Any handbook on electrical subject provide this technical
detail).
Physical length(l) of busbar can easily be measured.
Resistnace(R) can be measured with the help of
ohmmeter.Since busbar resistane is of small order so we can
also use alternative to ohmeters which works satisfactorily
in small range of resistances.

A=(p*l)/R.

Answer / james bond

Area is simply width*depth,,hahaahah
if u dont know the length of busbar answer no. one fails..

simply u have to calculate the Area of bus bar required for
the given current rating or load kW, which is given in IS
standard.

why fuse amperes rating are specified ratings like 32amp & 64 amps?
