Find the equivalent resistance between point $A$ and $B$ in the following circuit. (The resistance of each resistor is $R$ )

• Correct answer
  A

  $\frac{34}{55} R$
• B

  $\frac{45}{77} R$
• C

  $\frac{3}{5} R$
• D

  $\frac{5}{3} R$

Solution

The equivalent resistance between point $A$ and $B$ is calculated as

Hence, the correct answer is option: 'A'.
