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 increased

Options

A. The bulb glows dimmer
B. the bulb glows brighter
C. total impedance of the circuit is unchanged
D. total impedence of the circuit increases

Answer

A, B, D

Explanation

`i_("rms") = (V_("rms"))/(sqrt(R^(2) + (1)/(omega^(2) C^(2))))` When `omega` increaeses, `i_("rms")` increases so the bulb glows brighter
