Expert Answer:

fraction numerator 1 over denominator R e f f end fraction equals fraction numerator 1 over denominator R 1 end fraction plus fraction numerator 1 over denominator R 2 end fraction plus fraction numerator 1 over denominator R 3 end fraction space equals fraction numerator begin display style 1 end style over denominator begin display style 3 end style end fraction plus fraction numerator begin display style 1 end style over denominator begin display style 3.5 end style end fraction plus fraction numerator begin display style 1 end style over denominator begin display style 4 end style end fraction equals 365 over 420 space space  R e f f equals fraction numerator begin display style 420 end style over denominator begin display style 365 end style end fraction space Ohms  V equals I e f f x R e f f I e f f space equals fraction numerator 8 x space 365 over denominator 420 end fraction space space A
