Exercise 86

An inductor ( L = 400 mH), a capacitor ( C = 4.43 µ F), and a resistor ( R = 500 ) are connected in series. A 50.0-Hz AC generator connected in series to these elements produces a maximum current of 250 mA in the circuit. (a) Calculate the required maximum voltage V max. (b) Determine the phase angle by which the current leads or lags the applied voltage.
