Three capacitors are connected as shown to the right. a) Calculate their equivalent capacitance, Ceq. b) Calculate the charge supplied by the 15 V battery. c) Calculate the voltage across and charge on C, C2, and C3. (Note: make a table) d) Calculate the energy needed to place the charges on the three capacitors. C1 = 6 UF C2 = 8 uF C3= 12 UF V = 15 V
