3 metal rods of same length and same area of cross section having the conductivities 1,2,3 units are connected in series. Then their effective thermal conductivity will be.....

Question

Umakant biswal · Answer

@ sreenidhi
can u remember to find out the effective resistance in the case of parallel combination of resister .
the same formula will going to be used in this case also .
k1 = 1
k2 = 2
k3 = 3

in series
k (eq)_ = 1/k1+1/k2+1/k3
= 1/1+1/2+1/3 = 11/6
so, final answer will be 6/11
beacuse 1/ k (eq ) = 11/6
HOPE IT CLEARS YOUR DOUBT
ALL THE BEST ..

l1+l2+l3/K=l1/k1+l2/k2+l3/k3 by using this formula,we get the final equivalent conductivity.Hope u will understand!!!
