In the circuit shown, if a conducting wire is connected between points $\mathrm{A}$ and $\mathrm{B}$, the current in this wire will:
- flow from $B$ to $A$
- flow from $A$ to $B$
- flow in the direction which will be decided by the value of $V$
- be zero
Solution
According to diagram
$
\begin{array}{r}
V_A-V_B=\left[V-\left(\frac{V}{8} \times 4\right)\right]-\left[V-\left(\frac{V}{4} \times 1\right)\right] \\
=-\frac{V}{2}+\frac{V}{4}=-\frac{V}{4}
\end{array}
$
$
\Rightarrow \quad V_B>V_A .
