The effective resistance between

A

and

B

, if resistance of each resistor is

R

, will be

Options

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

Correct answer

A. $\frac{8 R}{3}$

Step-by-step solution

From symmetry we can remove two middle resistance. New circuit is The effective resistance between A and B , if resistance of each resistor is R , will be
