Voltage Dropping Capacitor. It is used to drop the mains voltage to lower voltage. You would have gotten the same result if you had used a resistor in this configuration.
Or rearranging v q c. A capacitive power supply has a voltage dropping capacitor c1 this is the main component in the circuit. The voltage of c1 and c2 must sum to 6v.
This x rated capacitor is connected in series of phase line of ac to drop the voltage.
The concept of voltage drop comes into play when the same charged capacitor is connected to a circuit to utilize the stored energy. A small capacitance value will result in a larger voltage while a large value of capacitance will result in a smaller voltage drop. The voltage measured to be associated with the capacitor in such a discharging circuit is termed as the voltage drop. It is used to drop the mains voltage to lower voltage.
