Both batteries in Fig. 27-43a are ideal. Emf #1 of battery
Chapter , Problem 32(choose chapter or problem)
Both batteries in Fig. 27-43a 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 Fig. 27-43b 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 negativecurrent occurs when the direction of the current through the 21R2R1(a) 2 (V)Current (A)is0is5 10(b)21R2R1(a)+ +Figure 27-43 32.battery is opposite the direction of that batterys emf. What are (a)emf #1, (b) resistance R1, and (c) resistance R2?
