In the given circuit,the voltmeter records $5 \, V$. The resistance of the voltmeter in $ohms$ is

The figure shows a circuit having eight resistances of $1 \Omega$ each,labelled $R_1$ to $R_8$,and two ideal batteries with voltages $\varepsilon_1=12 V$ and $\varepsilon_2=6 V$. Which of the following statement$(s)$ is(are) correct?
$(A)$ The magnitude of current flowing through $R_1$ is $7.2 A$.
$(B)$ The magnitude of current flowing through $R_2$ is $1.2 A$.
$(C)$ The magnitude of current flowing through $R_3$ is $4.8 A$.
$(D)$ The magnitude of current flowing through $R_5$ is $2.4 A$.

The resistance between points $A$ and $B$ is

The total current supplied by the battery to the circuit is ............ $A$.

In the following circuit,the terminal voltage across the cell is (in $V$)

Two resistors whose values are in the ratio $2 : 1$ are connected in parallel with one cell. The ratio of power dissipated is:
