Accepted Answer

The given circuit can be redrawn as shown in the figure. It is a balanced Wheatstone bridge. No current will flow through $5 \Omega$ resistance, and hence it can be removed from the circuit. $3 \Omega$ and $2 \Omega$ resistances are in series. Hence we have two branches with $5 \Omega$ resistances each, connected in parallel. Their equivalent resistance is $2.5 \Omega$
$	herefore \quad \mathrm{I}=\frac{\mathrm{V}}{\mathrm{R}}=\frac{6}{2.5}=2.4 \mathrm{~A}$
