Two capacitors, C1 = 19.0 µF and C2 = 39.0 µF, are connected inseries, and a 18.0 V battery is connected across them.
(a) Find the equivalent capacitance, and the energy contained inthis equivalent capacitor. equivalent capacitance ( µF)
total energy stored (J)
(b) Find the energy stored in each individual capacitor. energystored in C1 3 J
energy stored in C2 ( J)
Show that the sum of these two energies is the same as the energyfound in part (a). Will this equality always be true, or does itdepend on the number of capacitors and their capacitances?
(c) If the same capacitors were connected in parallel, whatpotential difference would be required across them so that thecombination stores the same energy as in part (a)?
