Question

Calculate the equivalent resistance between the points A and B in the following

combination:​

Answer 1

Answer:

Let 4Ω, 4Ω and 4Ω are in series.

R

1

=4+4+4=12Ω

Now 2Ω, 2Ω and 2Ω are in series.

R

2

=2+2+2=6Ω

Now, R

1

=12Ω, R

2

=6Ω and 4Ω are in parallel.

R

R

3

=2Ω

Now between A and B, 5Ω, 2Ω and 6Ω are in series.

Resistance between A and B, R=5+2+6=13Ω

Hence, Equivalent resistance between A and B =13Ω
