Explanation:
When the 3 microfarad capacitor is charged to a potential of 300 volts, it stores an electric charge Q1 given by:
Q1 = C1 x V1
where C1 = 3 microfarad and V1 = 300 volts
Q1 = 3 x 10^-6 x 300
Q1 = 0.0009 coulombs
Similarly, when the 2 microfarad capacitor is charged to 200 volts, it stores an electric charge Q2 given by:
Q2 = C2 x V2
where C2 = 2 microfarad and V2 = 200 volts
Q2 = 2 x 10^-6 x 200
Q2 = 0.0004 coulombs
When the capacitors are connected in parallel:
When the capacitors are connected in parallel, the charge Q1 and Q2 will redistribute themselves until the potentials across both capacitors are equal. Let the final potential across both capacitors be Vf. Then we have:
Q1 + Q2 = Cf x Vf
where Cf is the equivalent capacitance of the two capacitors in parallel.
The equivalent capacitance Ceq is given by:
Ceq = C1 + C2
Ceq = 3 x 10^-6 + 2 x 10^-6
Ceq = 5 x 10^-6 microfarads
Substituting the values in the equation for charge, we get:
0.0009 + 0.0004 = 5 x 10^-6 x Vf
Vf = (0.0009 + 0.0004) / (5 x 10^-6)
Vf = 260 volts
Therefore, the final potential across both capacitors is 260 volts. The charge flow when the plates are connected is given by:
Qf = Cf x Vf
Qf = 5 x 10^-6 x 260
Qf = 0.0013 coulombs
Hence, the amount of charge that flows when the plates are connected is 0.0013 coulombs.
When the 3 microfarad capacitor is charged to a potential of 300 volts, it stores an electric charge Q1 given by:
Q1 = C1 x V1
where C1 = 3 microfarad and V1 = 300 volts
Q1 = 3 x 10^-6 x 300
Q1 = 0.0009 coulombs
Similarly, when the 2 microfarad capacitor is charged to 200 volts, it stores an electric charge Q2 given by:
Q2 = C2 x V2
where C2 = 2 microfarad and V2 = 200 volts
Q2 = 2 x 10^-6 x 200
Q2 = 0.0004 coulombs

When the capacitors are connected in parallel, the charge Q1 and Q2 will redistribute themselves until the potentials across both capacitors are equal. Let the final potential across both capacitors be Vf. Then we have:
Q1 + Q2 = Cf x Vf

0.0009 + 0.0004 = 5 x 10^-6 x Vf
Vf = (0.0009 + 0.0004) / (5 x 10^-6)
Vf = 260 volts
Therefore, the final potential across both capacitors is 260 volts. The charge flow when the plates are connected is given by:
Qf = Cf x Vf
Qf = 5 x 10^-6 x 260
Qf = 0.0013 coulombs
Hence, the amount of charge that flows when the plates are connected is 0.0013 coulombs.
