Current Electricity Charging Discharging Of Capacitors Question 671
Question: Two conductors AB and CD are connected between two parallel resistors in such a way that no current flows through them. Then a wire is connected between E and F.
Options:
A) There is no current in EF
B) Current flows from E to F
C) Current flows F to E
D) None of these
Show Answer
Answer:
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.
