The equivalent resistance between A and B for the mesh shown in the figure (with resistors of 4 $\Omega$, 8 $\Omega$, 8 $\Omega$, 4 $\Omega$ and 6 $\Omega$) is

Simplifying the network of resistors (4 $\Omega$, 8 $\Omega$, 8 $\Omega$, 4 $\Omega$, 6 $\Omega$) as arranged in the given mesh using series and parallel combination rules gives an equivalent resistance of $16\ \Omega$ between A and B.
