Qn.(6)

Equivalenet resistance 1Ω is less than all three given resistances 6Ω , 3Ω and 2Ω .

Hence all resistors should be connected in parallel.

If R1 , R2 , R3 are connected parallel , then equivalenet resistance is given as

Using above expression, we get equivalenet resistance of 6Ω , 3Ω and 2Ω connected in parallel as
