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

Options

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

Answer

B

Explanation

Current through arm CAD.

`I = V/8` amp
Potential difference between
C and `A = V_(C) - V_(A)`
`= V/8 xx 4 = V/2` Volt
Current through CBD `I. =V/4` amp
Potential difference between C and B = `V_( C) - V_(B)`
`=V/4 xx 1 =V/4` volt
`rArr V_(A) - V_(B) lt 0` or, `V_(A) lt V_(B)`
