1. 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.

2. 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.
