In the given circuit, the value of \( m \) is varying. The correct statements about the circuit are
(1) The condition for maximum current flowing from \( x \) is \( m=2 \).
(2) The maximum current is \( V / \sqrt{2} r \)
(3) The condition for maximum current flowing from \( x \) is \( m=\sqrt{2} \).
(4) The maximum current is \( 3 \mathrm{~V} / 2 r \).
