$A$ 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 $V$)

The battery in the diagram is to be charged by the generator $G$. The generator has a terminal voltage of $120 \ V$ when the charging current is $10 \ A$. The battery has an $emf$ of $100 \ V$ and an internal resistance of $1 \ \Omega$. In order to charge the battery at $10 \ A$ charging current,the resistance $R$ should be set at ................ $\Omega$.

$A$ cell of $e.m.f.$ $1.5\,V$ having a finite internal resistance is connected to a load resistance of $2\,\Omega$. For maximum power transfer,the internal resistance of the cell should be ............. $\Omega$.

Two electric bulbs marked $25 W-220 V$ and $100 W-220 V$ are connected in series to a $440 V$ supply. Which of the bulbs will fuse?

$A$ copper voltameter and a silver voltameter are connected in parallel. When a total charge $q$ flows through the voltameters,an equal mass of metal is deposited in each. If the electrochemical equivalents of copper and silver are $z_1$ and $z_2$ respectively,then the charge flowing through the silver voltameter is:

In the given circuit diagram,in the steady state,the current through the battery and the charge on the capacitor respectively are:
