The correct answer is:
$12 \mathrm{~S}$
Here, $R_1=1 / 2 \Omega, R_2=1 / 4 \Omega ; R_3=1 / 6 \Omega$
In parallel; $\frac{1}{R_p}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}=2+4+6=12$
or equivalent conductance, $G=\frac{1}{R_p}=12 \mathrm{~S}$
In parallel; $\frac{1}{R_p}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}=2+4+6=12$
or equivalent conductance, $G=\frac{1}{R_p}=12 \mathrm{~S}$
