Consider this circuit CAREFULLY. Look at the wiring and think which elements are in series and which elements are in parallel (DO NOT write explanations about what are in series/parallel, just think and solve the questions) C1 VB C2 C3 Suppose that VB= 15V: C1=10F: C2= 20F: & C3= 30F. a. what is the effective capacitance of the network? b. what is the voltage across C1? c. What is the charge stored in C3
