Explanation:
SOLUTION
The resistance is different for both the wires. As the length of the both the wires is same the electric field in wires and is same. Therefore potential in wires shall be linear function of .
At (i.e. at left end) . And at (i.e. at right end) potential of both wires must be same.
If we plot a graph taking along axis and along axis for both the wires, it will be a straight line.
Let and be the slopes of the graphs for wires and respectively.
At (i.e. at left end) , we can write
an
where, and potentials for wires A and B respectively.
Now, at (i.e. at right end) potential of both wires is same.
Hence,
where, a positive constant.
