After the switch is closed,the current drawn from the battery is (in $A$)

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

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

The total current supplied to the circuit by the battery is . . . . . . . (in $A$)

$A$ wire is broken into four equal parts. $A$ packet is formed by keeping the four wires together. The resistance of the packet in comparison to the resistance of the original wire will be:

The effective resistance between $A$ and $B$ in the figure is $\frac{7}{12} \Omega$ if each side of the cube has $1 \Omega$ resistance. The effective resistance between the same two points,when the link $A B$ is removed,is
