Question

The equivalent resistance between A and B is:

Options:

A .

0.5 Ω

B .

1 Ω

C .

2 Ω

D .

4 Ω

Answer: Option B
:
B

Two parallel combination of resistors:
When going from A to B, the first two resistors are in parallel to each other and so are the next two. Therefore
$R_{p a r a l l e l}$ = $\frac{1 \times 1}{1 + 1}$ = $\frac{1}{2} Ω$ for both of them.
Now these equivalent resistors are in series with each other
Therefore, net equivalent resistance is:
$R = 0.5 + 0.5 = 1 Ω$
