Answer 1

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