light bulb has a resistance of 260 . It is connected to a standard wall socket (120 V rms, 60.0 Hz).
(a) Determine the rms current in the bulb.
(b) Determine the rms current in the bulb after a 18.0 µF capacitor is added in series in the circuit.
(c) It is possible to return the current in the bulb to the value calculated in part (a) by adding an inductor in series with the bulb and the capacitor. What is the value of the inductance of this inductor?
