Capacitor Basic Calculations
So here we have a 9V battery and two capacitors with a total capacitance of 230uF. As this is parallel, this wire is 9V and this is 0V so both capacitors are charged to 9V. Therefore 0.00023 F multiplied by 9V = 0.00207 coulombs. And, with the three capacitors, we have 330uF (0.00033 F) multiplied by 9V = 0.00297 coulombs. ...
