The resistance of solution A is 50 ohm and that of B is 100 ohm. Both are taken in same cell. If equal volume of A and B are mixed and the mixture is taken in same cell then the resistance is

A

150 ohm

B

75 ohm

C

66.67 ohm

D

33.3 ohm

Text Solution

Verified by Experts

The correct Answer is:
B
Cell constant =`(l)/(a)=x`
when equal volume are mixed net `k=(x)/(50)+(x)/(100)//2` so net resistance R=66.7 ohm
