Question

Find equivalent resistance between points A and B for the network shown in the figure.
​

Answer 1

Answer:

First find the resistance of middle they are connected into series

R

S

=3R+3R

R

S

=6R

And this 6R resistor is parallel to B side resistor

R

P

=

6R+3R

3R×6R

==2R

So finally resistance between A and B is

R

S

1

=2R+R=3R

Hence,
