Question by Giancoli, Douglas C., Physics: Principles with Applications, 7th Ed., ©2014, Reprinted by permission of Pearson Education Inc., New York.
Problem 66
Q

When the resistor RR in Fig. 19–73 is 35  Ω35 \; \Omega, the high-resistance voltmeter reads 9.7 V. When RR is replaced by a 14.014.0-Ω\Omega resistor, the voltmeter reading drops to 8.1 V. What are the emf and internal resistance of the battery?

Problem 66.
Figure 19-73.
A
r=5.3  Ω,ξ=11 Vr = 5.3 \; \Omega, \xi = 11 \textrm{ V}

Hi, my textbook has problems from 1 through 87, but I only see 66 in here. Where do I access the others?
