1.

you are given three resistance of 1ohm, 2ohm,3ohm how with the help pf these resistance you can get 6ohm,6/11ohm,1.5ohm

Answer»

et 6 ohm       We  connect the three resistors in SERIES.  so resistances are added to get the effective resistance:  1 + 2 + 3 = 6 Ω2)  to get  6/11 Ω       We connect all the resistances in parallel.  The effective resistance be R.             1/R = 1/1 + 1/2 + 1/3 = 11/6                  R = 6/11 Ω3)  to get  1.5 Ω         We connect  1 Ω and 2 Ω in series.  Hence, resistance of the two will be 3 Ω.  Then connect the  3 Ω resistance in  parallel with the series connection of 1 Ω and 2 Ω.               so effective resistance  =  R                   1/R =  1/(1+2)  + 1/3 = 2/3                   R = 3/2 Ω = 1.5 Ω
