Question

Find the equivalent resistance between $A$ and $B$. Each resistor has same resistance $R$.

• A. $\frac{8}{5}R$
• B. $\frac{6}{5}R$
• C. $\frac{7}{5}R$
• D. $\frac{4}{5}R$

Answer 1

Answer: (D)

The current in $CO,OE,DO$, and $OF$ will be same.
So these branches will not touch each other at $O$.
