Walker, Halliday & Resnick β Circuits: Problem 48
48 In Fig. 27-47a, resistor 3 is a variable resistor and the ideal battery has emf \(\mathcal{E} = 18 \text{ V}\). Figure 27-47b gives the current \(i\) through the battery as a function of \(R_3\). The horizontal scale is set by \(R_{3s} = 20\ \Omega\). The curve has an asymptote of \(2.0 \text{ mA}\) as \(R_3 \to \infty\). What are (a) resistance \(R_1\) and (b) resistance \(R_2\)?
