    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.
