`A` and `B` are two points on a uniform ring of resistance `R`. The `/_ ACB = 90^@`, where `C` is the center of the ring. The equivalent resistance between `A` and `B` is.

Options

A. `(3 R)/(4)`
B. `(3 R)/(8)`
C. `(3 R)/(16)`
D. `(3 R)/(32)`

Answer

C

Explanation

`R_(AB) = ((R)/(4).(3R)/(4))/(R) = (3R)/(16)`.
