Question

What is the effective resistance between the points A and B

Answer 1

Explanation:

Equivalent circuit of the above figure is shown which shows that the three resistances are connected in parallel.

Thus equivalent resistance between A and B, \dfrac{1}{R_{eq}} = \dfrac{1}{R}+\dfrac{1}{R}+\dfrac{1}{R}
