Solution:
In the given figure, the effective resistance in both the parallel wires are equal $\left(b o t h = 5 \Omega\right)$ . Hence, the current divided in both the wires will be equal i.e., $2A$ will get divided in both the wires equally.
Now, by applying Ohm's law $\left(V = iR\right)$ ,
$V_{x}=\left(\right.1A\left.\right)\times \left(\right.2\Omega\left.\right)=2volts$
$V_{y}=\left(\right.1A\left.\right)\times \left(\right.3\Omega\left.\right)=3volts$
$\Rightarrow \text{V}_{y}\text{-V}_{x}\text{=3-2=1V}$
