An Alternating Voltage Source of Variable Angular Frequency ‘w’ and Fixed Amplitude ‘V’ is Connected in Series | Bzziii

An alternating voltage source of variable angular frequency ‘w’ and fixed amplitude ‘V’ is connected in series with a capacitance C and electric bulb of resistance R(inductance zero). When ‘w’ is increased- 

(i) The bulb glows dimmer. 

(ii) The bulb glows brighter. 

(iii) Net impedance of the circuit remains unchanged. 

(iv) Total impedance of the circuit increases.

(ii) The bulb glows brighter.
