Answer 1

$1) frac{1}{r456} = frac{1}{33 + 33} + frac{1}{33} = frac{1}{22} \ r456 = 22$
$2) frac{1}{r23456} = frac{1}{22 + 33} + frac{1}{33} = frac{8}{165} \ r23456 = frac{165}{8}$
$3)rtotal = frac{165}{8} + 33 = 193 frac{5}{8}$
$4)u = ri \ i = frac{u}{r} = frac{250}{193 timesfrac{5}{8} } = frac{2000}{1549}$
