A) There is no current in EF
B) Current flows from E to F
C) Current flows F to E
D) None of these
Correct Answer: B
Solution :
[b] As there is no current through, AB, all the points of AB are at the same potential, say \[{{V}_{1}}\]for the same reason all the points of CD are at the same potential, say\[{{V}_{2}}\], but \[{{V}_{1}}\]>\[{{V}_{2}}\] because current is flowing from A to C or B to D. therefore, \[{{V}_{E}}>{{V}_{F}}\]. This is why on connecting E and F by a wire, current will flow from E to F. Hence choice (2) is correct.
