If none of the capacitors shown can have more than 74 V across them, what is the maximum energy that can be stored in the 3-capacitor system? Give your answer in mJ (1mJ = 10- J). The capacitor values are C = 12 F, C = 22 F and C3 = 38 F. Emax = 61.1 61.2 mJ What is the charge stored in the 3-capacitor system when the maximum allowable voltage is applied from a to b. Qmax = Hint: First calculate the equivalent capacitance for the 3 capacitors in series. The same amount of charge will appear across each capacitor (because they are in series). The voltage across each one will be this amount of charge divided by its capacitance. Since the total applied voltage from a to b is not given, you can calculate the charge per volt (let Vab 1V). This will show you which capacitor has the greatest voltage across it. If this capacitor's voltage were equal to the maximum allowable, what would Vab become? Knowing Vab will set the total charge, from which the energy can be calculated: 1 Q2 2 C C C Ca If none of the capacitors shown can have more than 74 V across them, what is the maximum energy that can be stored in the 3-capacitor system?
