HEYA DEAR HERE IS YOUR ANSWER
--------------
(A) RESISTANCE OF EACH PART= R/4 OHM
(B) IF THEY ARE CONNECTED IN PARALLEL THAN
ITS EQUIVALENT RESISTANCE
= VALUE OF RESISTANCE/NO OF RESISTANCE
= R/4/4
=R/16 OHM

(a) R/4
(b) if connected in parrele
then. .
1/R'=1/R+1/R+1/R+1/R
1/R'= (1+1+1+1)/R
1/R'=4/R
R'=R/4
(b) if connected in parrele
then. .
1/R'=1/R+1/R+1/R+1/R
1/R'= (1+1+1+1)/R
1/R'=4/R
R'=R/4
