An RLC circuit such as that of Figure (a) has R = 4.870, C = 20.5 µF, L = 1.34 H, and Em = 25.0 V. (a) At what angular frequency wa will the
current amplitude have its maximum value, as in the resonance curves of Figure (b)? (b) What is this maximum value? At what (c) lower
angular frequency wd₁ and (d) higher angular frequency Wd2 will the current amplitude be half this maximum value? (e) What is (waz -
wa1)/wa, the fractional half-width of the resonance curve for this circuit?
