Question

the cross section of a composite cylindrical bar of section A and B of same material and same length having radii R and R respectively are as shown below if a constant current is flowing through it then the ratio of potential difference across section A and B each

Answer 1

can you elaborate please

Answer 2

Answer:

1:1

Explanation:

If the wires is made up of same material and have same length and both have a same radius i.e 'R' then, the resistance for both is equal.

       Hence,  $\frac{V_{A}}{V_{B}}$=$\frac{I X R}{1X R}$=$\frac{1}{1}$

You wrote in your question "as shown below". I cannot find it!!!
