Solution
The correct option is
A
15
2
Ω
The given circuit can be redrawn as:
Here,
3
Ω
and
6
Ω
are in parallel with each other. Their net resistance is given by :
R
=
6
×
3
6
+
3
=
2
Ω
Therefore, the above circuit can be further simplified as :
Hence, the net resistance between
A
and
B
is :
R
A
B
=
10
×
30
10
+
30
=
