Two identical plate capacitors each with the capacity C = 0.01μF are connected in parallel. The capacitors were charged to a voltage of U = 300 V and disconnected from the voltage source. The plates of one of the two capacitors were then pushed apart to a distance twice the original plate distance. What charge flows through the wires?
The charge on both the capacitors remain constant after
disconnection. The potential will be same across the capacitor. One
of the capacitors will have its capacitance reduced by half when
separation of plates is increased by a factor of two as stated in
the problem statement.
