Chapter 25, Problem 26(choose chapter or problem)
Capacitor 3 in Fig. 25-41a is a variable capacitor (its capacitance C3 can be varied). Figure 25-41b gives the electric potential V1 across capacitor 1 versus C3.The horizontal scale is set by C3s = 12.0 mF. Electric potential V1 approaches an asymptote of 10 V as C3 : . What are (a) the electric potential V across the battery, (b) C1, and (c) C2? VC2 C3C11086420C3 ( F) C3s Figure 25-41 26.
