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 th value of V
C. Be zero
D. Flow from B to A

Answer

D

Explanation

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