I have to calculate the voltage across a 50 uF (micro Farad) capacitor. The circuit voltage supply is 20V the capacitor is in series. There's an 100uF capacitor and 70uF capacitor parallel in the same circuit. I know that V=Charge/Capacitance however I don't know how to work out the charge to find the voltage. The capacitance of the circuit is 38.6uF
