$A$ resistor is connected to a battery of $12 \text{ V}$ emf and internal resistance $2 \text{ }\Omega$. If the current in the circuit is $0.6 \text{ A}$, the terminal voltage of the battery is: (in $\text{ V}$)

For the given circuit,the potential difference between $x$ and $y$ is ......... (in $V$)

If three bulbs $60\,W$,$100\,W$ and $200\,W$ are connected in parallel,then

For the previous objective,which of the following graphs is correct?

$A$ battery consisting of $6$ cells,each with an internal resistance of $0.5\, \Omega$ and an $e.m.f.$ of $2\, V$,is being charged by a $220\, V$ $D.C.$ mains using an external resistor of $10\, \Omega$. The charging current is: (in $, A$)

$A$ uniform metallic wire having resistance $4 \ \Omega$ is bent to form a square loop $(ABCD)$ (see figure). $A$ resistance of $2 \ \Omega$ is connected between points $B$ and $D$ and a battery of $2 \ V$ is connected across points $A$ and $C$ as shown in the figure. Now the value of current $(I)$ is: (in $A$)
