When a current of $16 \, A$ is passed through a $NaCl$ cell for $10 \, min$,what mass of $Na$ (in $g$) is deposited?

$A$ 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 $l = \dots\dots\dots\dots\,m$.

In the following circuit,if $V_A - V_B = 6\,V$,then the value of resistance $R$ (in $\Omega$) is ............... $\Omega$.

In the given network,the current through branch $BG$ is almost equal to ............ $A$.

$A$ car has a fresh storage battery of emf $12 \, V$ and internal resistance $2 \times 10^{-2} \, \Omega$. If the starter motor draws a current of $80 \, A$, then the terminal voltage when the starter is $ON$ is: (in $V$)

In the given circuit,the terminal potential difference of the cell is: (in $ V$)
