12 ohm , 8 ohm and 5 ohm resistors are connected in paralle connection since all these resistance are connected between same points
For parallel connection equivalent resistance is given by
fraction numerator 1 over denominator R e q end fraction equals fraction numerator 1 over denominator R 1 end fraction plus fraction numerator 1 over denominator R 2 end fraction space plus fraction numerator 1 over denominator R 3 end fraction p u t t i n g space t h e space v a l u e s space w e space g e t fraction numerator 1 over denominator R e q end fraction space equals space 1 over 12 plus 1 over 8 plus 1 fourth fraction numerator 1 over denominator R e q end fraction equals space fraction numerator 2 plus 3 plus 6 over denominator 24 end fraction space equals space 11 over 24 R e q space equals space 24 over 11 space equals space 2.18
