Problem
An AC voltage source of variable angular frequency ω and fixed amplitude V0 is connected in series with a capacitance C and an electric bulb of resistance R (inductance zero). When ω is increased
(1) the bulb glows dimmer
(2) the bulb glows brighter
(3) total impedance of the circuit is unchanged
(4) total impedance of the circuit increases
