Five conductors meet at a point $x$ as shown in the figure. What is the current flowing through the fifth conductor?

As the switch $S$ is closed in the circuit shown in the figure,the current passing through it is ............. (in $, A$)

The equivalent resistance of the following circuit when no current flows in the resistance of $5 \Omega$ is nearly (in $\Omega$)

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

In a Wheatstone network,$P=2 \Omega, Q=2 \Omega, R=2 \Omega$,and $S=3 \Omega$. The resistance with which $S$ is to be shunted so that the bridge may be balanced is: (in $\Omega$)

Figure $(i)$ below shows a Wheatstone's bridge in which $P, Q, R$ and $S$ are fixed resistances,$G$ is a galvanometer and $B$ is a battery. For this particular case,the galvanometer shows zero deflection. Now,only the positions of $B$ and $G$ are interchanged,as shown in figure $(ii)$. The new deflection of the galvanometer
