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?
Solutions
Expert Solution
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.

Two identical capacitors are connected in parallel, and each
acquires a charge Q0 = 1.12E-6 C when connected to a source of
voltage V0 = 2.45 V. The voltage source is disconnected, and a
dielectric with constant ? = 2.00 is inserted to fill the space
between the plates of one of the capacitors. What is the smaller of
the two final capacitor charges? What is the larger of the two
final charges? What is the final volatge across the...
