The current flowing through the circuit shown in the figure is ............ $A$.

Find the equivalent resistance between points $A$ and $B$ for the given circuit.

In the adjoining circuit,the battery $E_1$ has an $e.m.f.$ of $12 \, V$ and zero internal resistance,while the battery $E$ has an $e.m.f.$ of $2 \, V$. If the galvanometer $G$ reads zero,then the value of the resistance $X$ in $\Omega$ is

The current through the wire $XY$ of the circuit shown is ................ $A$.

The equivalent resistance between points $A$ and $B$ in the following circuit is:
