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
  • a)
    the bulb glows dimmer
  • b)
    the bulb glows brighter
  • c)
    total impedance of the circuit is unchanged
  • d)
    total impedance of the circuit increases
Correct answer is option 'B'. Can you explain this answer?
