There are two thermal resistors once in series once in parallel with thermal conductivity 3K and 6K both have same length and areaone side of the registers is hundred degree water and another side of the resistor is zero degree ice. They produce same amount of heat. If in the parallel it melts 9 gram of ice in 4 seconds. How much eyes it will melt in the series combination in 8 seconds?
a)2g
b)4g
c)6g
d)8g

Answer:
We know that for the given condition, equivalent thermal conductivity will be given as:
K=
L
1
K
2
+L
2
K
1
K
1
K
2
(L
1
+L
2
)
So putting these value in above formula we find,
K
eq
=
5KL
6K

(L)
=1.2K
