Step-by-step explanation

Given all resistances have same resistance R.

Now, we can redraw the circuit as below

JEE Main 2021 (Online) 26th February Morning Shift Physics - Current Electricity Question 212 English Explanation

Let resistances be R1, R2, R3 and R4.

So, circuit will behave as a Wheatstone bridge and no current will flow through middle resistor.
