Question

plz explain how I2 is found out?

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






A)
The current through PQ is zero






B)





C)
The potential atSis less than that at Q






D)





View Solution Answer: A,B,C,D Solution:
By symmetry of circuit P, Q are at same potential and S, T are also at same potential.









by the symmetry of the circuit.

.

flows from higher potential P to lower potential S.

Therefore, .
