Voltage Dropping Capacitor. As the charge q is equal and constant the voltage drop across the capacitor is determined by the value of the capacitor only as v q c. Or rearranging v q c.
A capacitor drops voltage only if it is used as a voltage divider in conjuction with another impedance. The main component of a transformer less power supply circuit is voltage dropping capacitor or x rated capacitor which are specially designed for ac mains. Use q cv and solve for the voltages.
A capacitor drops voltage only if it is used as a voltage divider in conjuction with another impedance.
The force is drag force kind of force exerted by the molecules of the insulator. This x rated capacitor is connected in series of phase line of ac to drop the voltage. So for equal charges in each capacitor voltage will be inversely proportional to capacitance.
