For the circuit shown in the figure,the equivalent resistance between $A$ and $B$ is ............. $\Omega$.

Two resistors $R_{1} = (4 \pm 0.8) \, \Omega$ and $R_{2} = (4 \pm 0.4) \, \Omega$ are connected in parallel. The equivalent resistance of their parallel combination will be

If the resistance between each dot is $R$,then the equivalent resistance between $A$ and $B$ is:

In the given figure,the $emf$ of the cell is $2.2 \, V$ and the internal resistance is $0.6 \, \Omega$. Calculate the power dissipated in the whole circuit (in $W$).

Twelve resistors each of resistance $16 \,\Omega$ are connected in the circuit as shown. The net resistance between $A$ and $B$ (any two conjugate points of the outer square) is ............... $\Omega$.

$A$ piece of wire is cut into four equal parts and the pieces are bundled together side by side to form a thicker wire. Compared with that of the original wire,the resistance of the bundle is ..........
