In the given circuit the power dissipated through resistance `R_(1) = 9 Omega` is `P_(1)`, when switch `S_(1)` is closed and `S_(2)` is opened and the power dissipated through resistance `R_(2) = 4 Omega` is `P_(2)`, when switch `S_(2)` is closed and `S_(1)` is opened. If `P_(1) = P_(2)`, then r is equl to :
