Resistors of $4\, R, 16\, R, 64\, R, \dots \infty$ are connected in series. Find their equivalent resistance.

In the given circuit,each resistor has a resistance of $2\,\Omega$. The equivalent resistance between $A$ and $B$ is ............ $\Omega$.

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

What is the equivalent resistance between $A$ and $B$?

$A$ wire has a resistance of $24 \ \Omega$ and is bent into the shape shown below. The effective resistance between $A$ and $B$ is ............. $\Omega$.

Consider the circuit shown below where all resistors are $1 \,k\Omega$. If a current of magnitude $1 \,mA$ flows through the resistor marked $X$,the potential difference measured between points $P$ and $Q$ is ..............$V$.
