Question
Two capacitors to 3 uF charged to a 100 V, and the other to 200 V. Determine the voltage between the plates, if the capacitors connected in parallel
Два конденсатора емкостью по 3 мкФ заряжены один до 100 В, а другой до 200 В. Определить напряжение между обкладками, если конденсаторы соединены параллельно.

Answers
C = Q/V
Q1 = 3*10^-6 * 100
Q2 = 3*10^-6 * 200
total Q = 900 * 10^-6 Coulombs
total C = 6*10^-6 farads
V = Q/C = 900/6 = 150 Volts
(We probably should have guessed that :)
