The rms current in the circuit below is shown as a function of the frequency of the driving Emf. Capacitor C = 0.250μF and the total resistance R = 243Ω.
(a) Calculate the rms value of the driving Emf. Note that the curve passes through a grid intersection point.
(b) Calculate the inductance in the circuit.
(c) Calculate the maximum average power dissipated in the circuit.
