What is the equivalent resistance between X and Y?

Expert Answer:

The equivalent resistance is just 2R.

As we can see in the figure, beyond the X and Y terminals and after the first resistances, there is a path (the vertical line, which represents low resistance) of low resistance, and the current will follow this path bypassing the other resistances. The we have only R and R, in series between X and Y.

Hence we see that the current will flow in the first loop only if a battery is connected across X and Y terminals.
