Solution:
Initial Charge on Capacitors
Initial charge on the 3 microFaraday capacitor with potential difference V1=300V is given by,
Q1 = C1 * V1 = 3 x 10^-6 F x 300 V = 0.9 mC
Initial charge on the 2 microFaraday capacitor with potential difference V2=200V is given by,
Q2 = C2 * V2 = 2 x 10^-6 F x 200 V = 0.4 mC
Total Charge on Capacitors
Total charge on the capacitors before they are connected in parallel is,
Qt = Q1 + Q2 = 0.9 mC + 0.4 mC = 1.3 mC
Charge Flow when Capacitors are Connected in Parallel
When the capacitors are connected in parallel, the plates of opposite polarity are joined together. The potential difference across the combination of capacitors will be the same as the potential difference across each capacitor, which is the same as the initial potential difference.
The equivalent capacitance of the combination of capacitors connected in parallel is,
Ceq = C1 + C2 = 3 x 10^-6 F + 2 x 10^-6 F = 5 x 10^-6 F
The charge on the combination of capacitors is given by,
Q = Ceq * V = 5 x 10^-6 F x 300 V = 1.5 mC
The charge flow when the plates are connected is the difference between the total initial charge on the capacitors and the charge on the combination of capacitors,
Qf = Q - Qt = 1.5 mC - 1.3 mC = 0.2 mC
Therefore, the amount of charge that flows when the plates of the capacitors are connected is 0.2 mC.
Initial Charge on Capacitors
Initial charge on the 3 microFaraday capacitor with potential difference V1=300V is given by,
Q1 = C1 * V1 = 3 x 10^-6 F x 300 V = 0.9 mC
Initial charge on the 2 microFaraday capacitor with potential difference V2=200V is given by,
Q2 = C2 * V2 = 2 x 10^-6 F x 200 V = 0.4 mC
Total Charge on Capacitors
Total charge on the capacitors before they are connected in parallel is,

When the capacitors are connected in parallel, the plates of opposite polarity are joined together. The potential difference across the combination of capacitors will be the same as the potential difference across each capacitor, which is the same as the initial potential difference.

The charge flow when the plates are connected is the difference between the total initial charge on the capacitors and the charge on the combination of capacitors,

Therefore, the amount of charge that flows when the plates of the capacitors are connected is 0.2 mC.
