A \( 110 \mathrm{~V}, 60 \mathrm{~W} \) lamp is run from a \( 220 \mathrm{~V} \) AC mains
P using a capacitor in series with the lamp, instead of a
W resistor then the voltage across the capacitor is about:-
(1) \( 110 \mathrm{~V} \)
(2) \( 190 \mathrm{~V} \)
(3) \( 220 \mathrm{~V} \)
(4) \( 311 \mathrm{~V} \)
