Question

The resistivity of two materials 'A' and 'B' are in the ratio of 2:3. If 10 m of 'A' is
taken, what should be the length of 'B' such that the resistance of 'A' and 'B' are
equal ? (Both 'A' and 'B' have same area of cross section)​

Answer 1

hope it will help you:-)

Answer 2

Answer:15

Explanation:

2:3=10:x

2/3=10/x

2x=30

X=30/2
