## AC Circuits

 What changes have to be made in Ohm's Law to use it in AC circuits? How do you find the impedance of the AC circuit elements: capacitors and inductors? How are impedances combined? How do you find the resonant frequency and resonant impedance of a series RLC circuit? How do you find the resonant frequency and resonant impedance of a parallel RLC circuit? How do you calculate parallel impedance when capacitors or inductors are involved? Describe the RC high pass filter in terms of its break point and its attenuation for different frequencies. How do you calculate the output from a voltage divider? How does an AC voltage divider differ from the DC divider? How do you calculate equivalent circuits for AC circuits? How is the selectivity or "Q" of a resonant circuit obtained? *AC Ohm's Law *RMS Values *Impedance *Capacitive Reactance *Inductive Reactance *RC Circuit *RL Circuit *Phasors *RLC Circuit *Resonance *Series Resonance *RLC Parallel *Parallel Resonance *Complex Impedance *Parallel Combinations *Rationalization of Complex Numbers *Series-Parallel *RC High Pass Filter *RC High Pass Calculation *DC Voltage Divider *AC Voltage Divider *AC Thevenin Equivalent
