In the following circuit,the current through the resistor $R(=2 \Omega)$ is $I$ Amperes. The value of $I$ is

In the electric network shown,when no current flows through the $4\, \Omega$ resistor in the arm $EB$,the potential difference between the points $A$ and $D$ will be ............... $V$.

Consider the circuit shown in the figure. Find the current through the $10\,\Omega$ resistor when the switch $S$ is $(a)$ open $(b)$ closed.

$A$ straight wire of resistance $R$ is bent into the shape of a square. $A$ cell of emf $12 \text{ V}$ is connected between two adjacent corners of the square. The potential difference across any diagonal of the square is (in $\text{ V}$)

In the given figure,the steady state current $I$ is ................. $A$.

In the figure shown,the capacity of the capacitor $C$ is $2\,\mu F$. The current in the $2\,\Omega$ resistor is ............... $A$.
