The equivalent resistance of the circuit shown below between points $a$ and $b$ is $..........\Omega$

In the network shown in the following figure,each resistance is $1\,\Omega$. The effective resistance between $A$ and $B$ is

Two resistance wires on joining in parallel the resultant resistance is $\frac{6}{5} \ \Omega$. One of the wires breaks,the effective resistance is $2 \ \Omega$. The resistance of the broken wire is ............ $\Omega$.

The effective resistance between the points $A$ and $B$ in the figure is ............. $\Omega$.

The equivalent resistance between the points $A$ and $B$ is:

Three resistances,each of $1\,\Omega$,are joined in parallel. Three such combinations are put in series,then the resultant resistance will be ............. $\Omega$.
