The equivalent resistance between $P$ and $Q$ in the given figure is ............... $\Omega$.

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

In the given circuit diagram,the currents $I_1 = -0.3\,A$,$I_4 = 0.8\,A$ and $I_5 = 0.4\,A$ are flowing as shown. The currents $I_2, I_3$ and $I_6$ respectively are

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

In the circuit shown,the current in the $1\,\Omega$ resistor is
