Question:
Both batteries in Figure a are ideal. Emf ?1 of battery 1 has a fixed value, but emf ?2 of battery 2 can be varied between 1.0 V and 10 V. The plots in Figure b give the currents through the two batteries as a function of ?2. The vertical scale is set by is = 0.20 A. You must decide which plot corresponds to which battery, but for both plots, a negative current occurs when the direction of the current through the battery is opposite the direction of that battery's emf. What are?
(a) Emf ?1,
(b) Resistance R1, and
(c) Resistance R2?
