In the given circuit (as shown in figure),

Study the following circuit diagrams in figures and select the correct options.

Two circuits (as shown in the figure) are called circuit $A$ and circuit $B$. The equivalent resistance of circuit $A$ is $x$ and that of the circuit $B$ is $y$ between $1$ and $2$.

For the circuit shown in figure, select the correct statements from the following options.

In the given circuit (figure),

In the circuit shown (figure), the cell is ideal with $\mathrm{emf}=2 \mathrm{V}$. The resistance of the coil of the galvanometer $G$ is $1 \mathrm{\Omega }$. Then

In the circuit shown in figure, $E_1$ and $E_2$ are two ideal sources of unknown emfs. Some currents are shown. Potential difference appearing across $6 \mathrm{\Omega }$ resistance is $V_A-V_B=10 \mathrm{V}$.
