Answer 2

Explanation:

For parallel combination of resistance,

we know that ,

$\frac{1}{ R} = \frac{1}{ R1} + \frac{1}{R2 } + \frac{1}{R3} ..............$

Given ,

R1 = 2 ohm

R2 = 4 ohm

R3 = 8 ohm

According to the question ,

$\frac{1}{ Rnet} = \frac{1}{2} + \frac{1}{4} + \frac{1}{8} \\ \\ \frac{1}{ Rnet} = \frac{4 + 2 + 1}{8} \\ \\ \frac{1}{ Rnet} = \frac{7}{8} \\ \\ Rnet = \frac{8}{7}$
