Chapter 27, Problem 019 A total resistance of 3.19 Ω is to be produced by connecting an unknown resistance to a 12.12 Ω resistance. (a) What must be the value of the unknown resistance, and (b) should it be connected in series or in parallel?
As mentioned in question-
Total resistance < One of the resistance i.e that connection should be parallel with unknown resistance-
3.19 = R*(12.12) / (R + 12.12)
3.19R + 38.66 = 12.12R
8.93 R = 38.66
R = 4.33 ohm
Thankyou !!! Have Fun
Please Rate High.

*Chapter 27, Problem 012 The figure shows a resistor of resistance R = 6.00 Ω connected to an ideal battery of emf E = 15.2 V by means of two copper wires. Each wire has length 21.7 cm and radius 1.80 mm. In dealing with such circuits in this chapter, we generally neglect the potential differences along the wires and the transfer of energy to thermal energy in them. Check the validity of this neglect for the circuit of the...
