100\,\text{V(rms)}

source is connected to a series circuit containing a

20\,\Omega

resistor, a

0.20\,\text{H}

inductor and an

80\,\mu\text{F}

capacitor. (i) The rms current is observed to be

4.0\,\text{A}

. Calculate the two possible angular frequencies (to two significant figures) at which this can occur. (ii) Convert these angular frequencies to the corresponding frequencies in hertz.
