The resistance between the terminal points $A$ and $B$ of the given infinitely long circuit will be

In the circuit shown, the value of each resistance is $r$. Then equivalent resistance of circuit between points $A$ and $B$ will be

The potential difference across $8 \mathrm{\Omega }$ resistance is $48 \mathrm{V}$, as shown in the figure. The value of potential difference across $X$ and $Y$ points will be

The resistance of the series combination of two resistance is $S$. When they are joined in parallel, the total resistance is $P$. If $S=nP$, then the minimum possible value of $n$ is
