A lamp connected in series with a capacitor and an AC voltage source will light up. This is because:  



▸

the dielectric is shorted out automatically when alternating current is applied.



▸

the peak AC voltage, being higher than the equivalent DC voltage, can temporarily break down the dielectric.



▸

the lamp is also acting as a capacitor when connected in series with an actual capacitor.



▸

the capacitor is being alternately charged and discharged, resulting in a continuous flow of current through the lamp.
