The storage battery of a car has an emf of $12 \ V$. If the internal resistance of the battery is $0.6 \ \Omega$,then the maximum current that can be drawn from the battery is . . . . . . . (in $A$)

The power of an electric motor is $242 \ W$ when connected to a $220 \ V$ supply. When the motor is operated at $200 \ V$,the current drawn by it is (in $A$)

In the circuit shown in the figure,the current flowing in the $2\,\Omega$ resistance is ............... $A$.

In the given circuit,the current through $2 \ \Omega$ resistor is

Which arrangement of four identical resistances should be used to draw maximum energy from a cell of voltage $V$?

$A$ straight wire of resistance $R$ is bent into the shape of a square. $A$ cell of emf $12 \text{ V}$ is connected between two adjacent corners of the square. The potential difference across any diagonal of the square is (in $\text{ V}$)
