The current $I_{1}$ (in $A$) flowing through the $1\; \Omega$ resistor in the following circuit is:

The equivalent resistance between $A$ and $B$ for the mesh shown in the figure is ......... $\Omega$.

The equivalent resistance of the circuit shown in the figure is ............. $\Omega$

What is the equivalent resistance across $A$ and $B$ in the figure shown,if $R = 3\,\Omega$?

The equivalent resistance between $A$ and $B$ is $:-$

You are given several identical resistances each of value $R = 10\,\Omega$ and each capable of carrying a maximum current of $1\,A$. It is required to make a suitable combination of these resistances to produce a resistance of $5\,\Omega$ which can carry a current of $4\,A$. The minimum number of resistances of the type $R$ that will be required for this job is:
