Question

In the circuit shown below, all the resistances are equal, each equal to R. The equivalent resistance between points A and C is :

• A. R
• B. 4R
• C. R/2
• D. None of the above

Answer 1

The correct option is D None of the above

$R_{AC}=\frac{5R}{3}\parallel \frac{5R}{3}{R}_{AC}=\frac{25R^2}{30R}=\frac{25}{30}R$
