PMT - 1996

Five resistors are connected as shown in the diagram. The equivalent resistance between A and B is  

(1) 6 ohm

(2) 9 ohm

(3) 12 ohm

(4) 15 ohm

(1) Since the given bridge is balanced, hence there will be no current through 9Ω resistance. This resistance has no effect and must be ignored in the calculations.

RAB=9×1827=6Ω
