Current Electricity and Electrical InstrumentHard

Question

For the resistance network shown in the figure, choose the correct option(s)
     

Options

A.The current through PQ is zero.
B.I1 = 3A
C.The potential at S is less than that at Q.
D.I2 = 2A

Solution

           
Nodes P and Q are equipotential and nodes Sand T are equipotential from wheatstone bridge,no current passes through PQ and ST.
