Answer 1

Answer:

hey mate here is your answer:

Explanation:

from the figure we can concude that R,2R is in series

so,

Req.=2R+R=3R

similarly,.

R and 2 R are in seies

so,

r eq=R+2R=3R

Also,

3R,3R and R in parallel

$r.eq = \frac{1}{3r} + \frac{1}{3r} + \frac{1}{r}$

$= \frac{r + r + 3r}{3r}$

$= \frac{6r}{3r}$
