The brightness of a bulb will be reduced,if a resistance is connected in

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 ............... $\Omega$.

The power consumed when $10 \ V$ voltage is applied to a series combination of $10$ resistors of each $1 \ \Omega$ is $P_{s}$ and the power consumed when the same $10 \ V$ is applied to the parallel combination of these $10$ resistors is $P_p$. The value of $\frac{P_{s}}{P_{p}}$ is

Two resistors are joined in parallel,and their resultant resistance is $\frac{6}{5} \,\Omega$. One of the resistance wires is broken,and the effective resistance becomes $2 \,\Omega$. Then the resistance (in $\Omega$) of the wire that got broken is ..........

In the given circuit,the equivalent resistance between $A$ and $B$ is ....... $\Omega$.

$A$ ring is made of a wire having a resistance $R_0 = 12 \,\Omega$. Find the points $A$ and $B$,as shown in the figure,at which a current-carrying conductor should be connected so that the resistance $R$ of the sub-circuit between these points is equal to $\frac{8}{3} \,\Omega$.
