Which 2 junctions to connect to ahieve greatest resistance?

Solutions: B

Based on individual calculations, the highest effective resistance will only be achieved if the junctions are connected at Q and S.

(NOT connected diagonally at Q and S, which some students thought initially, as it will be short circuit and the resistors are redundant)

Important concepts which you have to know total effective resistance of parallel circuit. Refer to the image below.
