plz slove this .............​

Answer 1

Answer:

Option A - R/2 is the correct answer.

Explanation:

Since, the above circuit follow wheet stone bridge for the upper part. So, R in the middle can be neglected.

So, We have the resistances connected in parallel, with above two as 2R each and R the remaining one.

So, 1/Re = 1/2R + 1/2R + 1/R

1/Req = 4/2R

Req = R/2

So, the answer is R/2 ohms
