Capacitance Potential Divider: In a parallel circuit containing multiple capacitors, the capacitance potential divider formula calculates the voltage across each capacitor. The formula, V = Vin * (C / (Ctotal)), determines the voltage (V) across a specific capacitor (C) based on the input voltage (Vin) and the total capacitance of the circuit (Ctotal). This formula enables the determination of voltage distribution across capacitors, which is crucial for understanding circuit behavior in electronic systems.
