Question

The effective resistance between A and B in the given circuit is??​

Answer 1

Correct option is D)

Starting from the extreme right direction:

The three 2Ω resistor are in series and parallel to 3Ω resistor.

R

s

=2+2+2=6Ω

R

p

1

=

6

1

+

3

1

R

p

=2Ω

Again, the three 2Ω resistor are in series and parallel to 3Ω resistor.

R

s

=2+2+2=6Ω

R

p

1

=

6

1

+

3

1

R

p

=2Ω

Now,The three 2Ω resistor are in series, between A and B,

R

s

=2+2+2=6Ω
