    2. For a series electrical circuit with resistance R, inductance L and capacitance C, the total
    impedance z is given by
    z = R + jωL +1/jωC
    ,
    where j^2= −1 and ω represents angular frequency.
    a) Resonance occurs when ℑ{z} = 0, where ℑ{·} denotes imaginary part.
    Determine the resonant angular frequency ω = ωr, in terms of L and C, where ωr > 0.
