. The equivalent resistance between the points P and Q of the circuit given is                                        [Pb. PMT 2002]

A)         \[\frac{R}{4}\]

B)         \[\frac{R}{3}\]

C)         4 R

D)         2 R

Correct Answer: B

Solution :

                                         All of three resistance are in parallel So, \[R'=R/n=\frac{R}{3}\].
