A battery of two capacitors, the first with a capacity of C1=3*10^-10F and the second with a capacity of C2=4.5*10^-10F, connected in series, was connected to a power source with an EMF of 200V. Then the battery was disconnected from the network, and the capacitors were connected in parallel. What is the voltage at the terminals of the resulting capacitor battery?

Detailed solution with a brief entry of the condition, formulas and laws used in the solution, derivation of the calculation formula and the answer. If you have any questions about the solution, write. I will try to help.
