In the circuit shown if a conducting wire is connected between points A and B, the current in this wire will :-

Options

A. flow from A to B
B. flow in the direction which will be decided by the value of V
C. be zero
D. flow from B to A

Answer

4

Explanation

`V_(A)-V_(B)=[V-((V)/(8)xx4)]=[V=((V)/(4)xx1)]`
`=-(V)/(2)+(V)/(4)=-(V)/(4)rArr V_(B)gtV_(A)rArr`
