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

In the circuit shown,the potential difference between $X$ and $Y$ will be ............. $V$.

Two bulbs,as in the previous context ($40\, W$ and $100\, W$ bulbs rated at the same voltage),are connected in series to a $200\, V$ line. Then:

$A$ $9\, V$ battery with an internal resistance of $0.5\,\Omega$ is connected across an infinite network as shown in the figure. All ammeters $A_1, A_2, A_3$ and the voltmeter $V$ are ideal. Choose the correct statement.

In the figure shown,the total resistance between $A$ and $B$ is ............. $\Omega$.

If two bulbs of wattage $25\, W$ and $100\, W$ respectively,each rated at $220\, V$,are connected in series with a supply of $440\, V$,then which bulb will fuse?
