Question

Find equivalent resistance between A and B

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

Answer 1

The correct option is C

$\frac{R}{2}$

Given circuit can be redrawn as follows

Since the circuit is a simple parallel combination where each branch has a resistance of $R$, therefore equivalent resistance will be $R/2$.
