$A$ battery of $emf$ $8 \ V$ and internal resistance $0.5 \ \Omega$ is being charged by a $120 \ V$ $dc$ supply using a series resistor of $15.5 \ \Omega$. The terminal voltage of the $8 \ V$ battery during charging is (in $V$)

In the circuit shown in the adjoining figure,the reading of ammeter $A$ is ................ $A$.

The resistance of an ideal voltmeter is

$A$ voltmeter of very high resistance is connected in the circuit as shown in the figure. The voltage shown by this voltmeter will be . . . . . . . (in $V$)

$A$ $25\, W$,$220\, V$ bulb and a $100\, W$,$220\, V$ bulb are connected in series across a $220\, V$ line. Which electric bulb will glow more brightly?

$A$ uniform metallic wire carries a current of $2\,A$ when a $3.4\,V$ battery is connected across it. The mass of the uniform metallic wire is $8.92 \times 10^{-3}\,kg$,its density is $8.92 \times 10^3\,kg/m^3$,and its resistivity is $1.7 \times 10^{-8}\,\Omega\cdot m$. The length of the wire is $l = \dots\dots\dots\dots\,m$.
