They're not in phase, so you can't simply subtract their amplitudes. The current through the resistor will be somewhat out of phase with the voltage of the AC voltage source due to the fact that the resistor is in a series circuit with an inductor and capacitor. With problems of this type you always have to remember that you're dealing with different voltages and currents that are generally out of phase with each other. | |
