Answer:
r
Explanation:
"There are 4 resistors placed in the form of a parallelogram . the four sides are mentioned r, in ABCD. Now we have to calculate the equivalent resistance between A and C, for this,
AB and BC in series
r + r = 2r
AD & CD is series
r + r = 2r
We know that AB and BC are in series and AD and CD are in series
= 1/(1/2r + 1/2r)
= 2r(1 + 1)
= 2r/2
= r
So the equivalent resistance across A and C is r"
