What will be the equivalent resistance of circuit shown in figure between points

Question

What will be the equivalent resistance of circuit shown in figure between points A and D

Options:

A . 10Ω

B . 20Ω

C . 30Ω

D . 40Ω

Answer: Option C
:
C
The equivalent circuit of above fig between A and D can be drawn as

R_{e q} = 10 + 10 + 10 = 30 Ω
