Each of the resistances in the network shown in the figure is equal to $R$. The resistance between the terminals $A$ and $B$ is

Four bulbs $B_1, B_2, B_3$ and $B_4$ of $100\, W$ each are connected to a $220\, V$ main supply as shown in the figure. The reading in an ideal ammeter will be ............... $A$.

The figure shows a network of resistances and cells in which the point $A$ is earthed. The point which has the least potential is

$A$ circuit is comprised of eight identical batteries and a resistor $R = 0.8\,\Omega$. Each battery has an $emf$ of $1.0\, V$ and internal resistance of $0.2\,\Omega$. The voltage difference across any of the batteries is ............. $V$.

In the circuit shown in the figure,all cells are ideal. The current through the $2 \, \Omega$ resistor is ............ $A$.

If the power dissipated in the $3\,\Omega$ resistor is $27\,W$,then what is the power dissipated in the $2\,\Omega$ resistor (in $,W$)?
