An AC voltage source of variable angular frequency `(omega)` and fixed amplitude `V_(0)` is connected in series with a capacitance C and an electric bulb of resistance R (inductance zero). When `(omega)` is increasedA. the bulb glows dimmerB. the bulb glows brighterC. total impendance of the circuit is unchangedD. total impendance of the circuit increases |

Answer» Correct Answer - B `(I_(rms))=(V_(rms))/(sqrt(R^(2)+(1/(omega C))^(2)))` As `(omega)` increses, `(I_(max))` increases. Therefore, the blub glows brighter. |
