A battery of $24$ cells, each of emf $1.5\, V$ and internal resistance $2\, \Omega$ is to be connected in order to send the maximum current through a $12 \,\Omega$ resistor. The correct arrangement of cells will be
A wire has resistance $12\,\Omega $. It is bent in the form of a circle. The effective resistance between the two points on any diameter is equal to ................ $\Omega$
$n$ identical bulbs, each designed to draw a power $p$ from a certain voltage supply, are joined in series across that supply. The total power which they will draw is
