Q. Consider the following statements regarding the network shown in the figure. 1. The equivalent resistance of the network between point A and B is independent of value of G. 2. The equivalent resistance of the network between points A and B is $\ \ \ \ \ \frac{4}{3}R$ 3. The current through G is zero. Which of the above statements is/zero true?

A) 1,2 and 3
B) 2 and 3
C) 2 alone
D) 1 alone
Explanation

(a) $R_{eff} = \frac{(P + Q)(R + S)}{(P + Q + R + S)} = \frac{4}{3}R$
