The value of current $I$ in the given current distribution is (in $A$)

The current drawn from the battery in the given network is (Internal resistance of battery is neglected) (in $A$)

$A$ Wheatstone bridge is used to determine the value of an unknown resistance $X$ by adjusting the variable resistance $Y$ as shown in the figure. For the most precise measurement of $X$,the resistances $P$ and $Q$:

The current from the cell for the given circuit is ................ $A$.

As shown in the circuit,if a conducting wire is connected between points $A$ and $B$,then the electric current in this wire will flow:

$A$ uniform wire of $16\,\Omega$ is bent into the form of a square. Two opposite corners of the square are connected by a wire of resistance $16\,\Omega$. The effective resistance between the other two opposite corners is ............... $\Omega$.
