Capacitor Voltage Divider Calculator

Calculate capacitive voltage divider circuits with impedance, frequency response, and energy storage analysis.

Capacitive Voltage Divider Formula:

V_out = V_in × C₁ / (C₁ + C₂) Note: C₁ is the upper capacitor (opposite to resistor dividers)

Vin = 5V

Vin = 12V

C1 = 100nF, C2 = 470nF

C1 = 1μF, C2 = 10μF
