Question

Find the equivalent resistance between points A
and B.
​

Answer 1

Circuit will act as wheat stone bridge, and current in 10Ω is zero.

R  

1

​  

=12Ω(∵4Ω & 8Ωinseries)

R  

2

​  

=6Ω(∵2Ω & 4Ωinseries)

R

R  

1

​  

×R

​  

=

12×6

​  

=4Ω(∵R

​  

 & R

Hence, Net resistance is 4Ω
