As (1/R)=(1/R)+(1/R)+(1/R)=(3/R) <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/83847038559fb477349bf79c95857310-.png" /> ∴ RN=R+(R/3)=(3 R+R/3)=(4/3) R

Q. The equivalent resistance between points $a$ and $b$ of a network shown in figure is given by

$\frac{3}{4} R$

$\frac{4}{3} k$

$\frac{5}{c} k$

$\frac{5}{1} R$

As $\frac{1}{R} = \frac{1}{R} + \frac{1}{R} + \frac{1}{R} = \frac{3}{R}$

$∴ R_{N} = R + \frac{R}{3} = \frac{3 R + R}{3} = \frac{4}{3} R$
