Q. Three resistances of values $2\Omega,\ 3\Omega$ and $6\Omega$ are to be connected to produce an effective resistance of $4\Omega.$ This can be done by connecting
A) $6\Omega$ resistance in series with the parallel combination of $2\Omega$ and $3\Omega$
B) $3\Omega$ resistance in series with the parallel combination of $2\Omega$ and $6\Omega$
C) $2\Omega$ resistance in series with the parallel combination of $3\Omega$ and $6\Omega$
D) $2\Omega$ resistance in parallel with the parallel combination of $3\Omega$ and $6\Omega$
Explanation
(c) These questions are done by hit and trial method only. You check all the options one by one till you get the final desired result
