Question

The effective resistance between A and B, if resistance of each resistor is R, will be

• A. $\frac{2R}{3}$
• B. $\frac{8R}{3}$
• C. $\frac{5R}{3}$
• D. $\frac{4R}{3}$

Answer 1

Answer: (B)

$\frac{8R}{3}$

Answer 2

From symmetry, we can remove two middle resistances. The new circuit configuration simplifies by eliminating these resistances, allowing us to analyze the remaining components more effectively.

Thus the correct answer is option 2.
