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

$A$ wire of length $l$ and resistance $100 \Omega$ is divided into $10$ equal parts. The first $5$ parts are connected in series while the next $5$ parts are connected in parallel. The two combinations are again connected in series. The resistance of this final combination is: (in $Omega$)

The equivalent resistance between the points $P$ and $Q$ in the network given here is equal to ................ $\Omega$ (given $r = \frac{3}{2} \Omega$).

Four equal resistors,each of resistance $10 \,\Omega$,are connected as shown in the circuit diagram. The equivalent resistance between $A$ and $B$ is ............. $\Omega$.

In the network shown in the figure,the equivalent resistance between points $X$ and $Y$ will be . . . . . . $\Omega$. The value of each resistor is $2 \Omega$.

Three resistances of equal values are arranged in four different configurations as shown below. Power dissipation in the increasing order is
