The two capacitors of the same capacity to 3 microfarads charged to a voltage of 100 V, and the other - to 200 V. To determine the voltage between the plates of a capacitor and energy capacitor system to the connection and after the connection, if connected in parallel: a) the same sign; b) oppositely charged electrodes.
Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
