Задача 30832.

A battery of two capacitors with a capacity of 3 * 10 ^ -10 and 4.5 * 10 ^ -10 F was connected in series, connected to a network with a voltage of 220 V. Then the battery was disconnected from the network, and the capacitors were connected in parallel. What is the voltage across the terminals of the resulting capacitor bank?

Detailed solution with a short recording of the conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the solution, write. I try to help.
