The figure below shows three capacitors with capacitances CA = 1.00 UF, Cp = 2.30 #F, and Cc = 4.40 #F connected to a 3.00-V battery. CA CB (a) What is the equivalent capacitance of the three capacitors? 1.88571 HF (b) What charge is stored in each of the capacitors? QA = UC QB HC ..U..... QC X Enter a number. "differs from the correct answer by more than 10%. Double check your calculations. HC (c) What is the potential difference across each of the capacitors? AVA = AVB = AVC =
