(i) In order to get a resistance of 9 from three resistors of 6 each, we connect two 6 resistors in parallel and then this parallel combination is connected in series with the third 6 resistor . For parallel connection: Or R= 3 And for series connection: R= 3 + 6 = 9 (ii) In order to get a resistance of 4 , their are multiple cases
(a) 1st Case
From three resistors of 6 each, we connect all the three 6 resistors in parallel:  Or R= 2 Then, Net Resistance R= 2 + 2 = 4 .
(b)2nd Case
We connect two resistors of 6 Ω in series and another resistor of 6 Ω in parallel to them
R= 6 Ω + 6Ω= 12Ω
Then Net Resistance Then R= 4 Ω Rate this question :
