$A$ 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 $V$)

If each resistor in the given figure is $9\, \Omega$,then the reading of the ammeter is .............. $A$.

In the given circuit,find the charge on the capacitors.

When the capacitor is fully charged,find the current drawn from the $9\, V$ cell (in $mA$).

Two sources of equal $emf$ $E$ are connected in series to an external resistance $R$. The internal resistances of the two sources are $R_1$ and $R_2$ $(R_2 > R_1)$. If the potential difference across the source having internal resistance $R_2$ is zero,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.
