In the given circuit,the current $I_1$ is .............. $A$.

The figure shows a network of four resistances and three batteries. Choose the correct alternative.

The figure shows a circuit diagram of a 'Wheatstone Bridge' to measure the resistance $G$ of the galvanometer. The relation $\frac{P}{Q} = \frac{R}{G}$ will be satisfied only when

In the given figure,the ratio of current in the $8\,\Omega$ resistor to the current in the $3\,\Omega$ resistor will be:

In the given circuit,if the voltage between points $B$ and $D$ is zero,then what is the value of resistance $x$ in $\Omega$?

As shown in the figure,for the balanced condition of the Wheatstone bridge,the value of $n$ is . . . . . .
