\frac{1}{R} = \frac{1}{5} + \frac{1}{3}

R = \frac{15}{8}

t o t s l r e s i s t a n c e = 8 + \frac{15}{8} + 6

= \frac{64 + 15 + 48}{8} = \frac{127}{8}

i = \frac{12}{\frac{127}{8}} = \frac{96}{127} a m p

c u r r e n t t h r o u g h r e s i s t a n c e 8 o h m = \frac{96}{127} a m p

c u r r e n t t h r o u g h 6 o h m = \frac{96}{127} a m p

\frac{1}{3} : \frac{1}{5}

= 5 : 3

c u r r e n t t h r o u g h 3 o h m = \frac{5}{8} \times \frac{96}{127} = \frac{60}{127} a m p

c u r r e n t t h r o u g h 5 o h m = \frac{3}{8} \times \frac{96}{127} = \frac{36}{127} a m p
