Chapter , Problem 34(choose chapter or problem)
The resistances in Figs. 27-45a and b are all 6.0 0, and the batteries are ideal 12 V batteries. (a) When switch S in Fig. 27-45a is closed, what is the change in the electric potential V1 across resistor 1, or does V1 remain the same? (b) When switch S in Fig. 27-45b is closed, what is the change in V1 across resistor 1,or does V1 remain the same?(a) (b)R1 R2SR1 R2R3S+Figure 27-45 34.
