Everything You Need to Know About Capacitor Polarity
Capacitors used in electronic devices can be categorized into polarized capacitors and non-polarized capacitors based on their polarity. Therefore, designers need to identify and correctly install capacitors'' polarity during circuit design to ensure the circuit''s normal operation and long-term stability.
$begingroup$ The question was exactly same and the assertion is the voltage control by inductance is preferred cause in case of resistance there is wastage of power(i^2r) and in case of pure capacitor there is flickering of bulb because of charging and discharging of capacitor.Hence best method is connecting inductance in series with bulb.
