The effect on voltage and current when capacitors are constructed in parallel in a circuit. By David Santo Pietro.
When capacitors are connected one after another, they are said to be in series. For capacitors in series, the total capacitance can be found by adding the reciprocals of the individual capacitances, and taking the reciprocal of the sum. Therefore, the total capacitance will be lower than the capacitance of any single capacitor in the circuit. Created by David SantoPietro.
