 For the circuit shown in the figure, calculate the resistance between points A and B

Answer:

Option B

Explanation:

Key idea (i)  Equivalent resistance in series combination,

$R_{eq}=R_{1}+R_{2}$+.....

(ii)    Equivalent resistance in parallel combination,

$\frac{1}{R_{eq}}= \frac{1}{R_{1}}+\frac{1}{R_{2}}+\frac{1}{R_{3}}+......$

As , the circuit is ,

.

Hence , the correct option is (b)
