## Answers ( )

Explanation:R = 5 ohm.

each portion of the diamaterical opposite to closed circle is equal to half of R that is 2.5ohm

effective resistance between the terminal across any of diameter of a circle.

R = ( 2.5 x 2.5 ) /5 = 2.5 / 2 = 1.25 ohm.

Answer:5/4

Explanation:5/2 and 5/2 will be in parallel

so,

equivalent resistance =

(5/2*5/2)/(5/2+5/2) = 5/4.
