What is meant by "reactance"? How do
you determine the reactance of a
capacitor? an inductor?
What form does Ohm's Law take for
reactive elements like capacitors
and inductors?
How is the phase of the current in
a capacitor related to the phase
of the voltage across the capacitor?
How is the phase of the current in
an inductor related to the phase
of the voltage across the inductor?
What is meant by impedance? What
is the unit of impedance?
How is the impedance of an RC series
circuit determined? an RL circuit?
How do you calculate the impedance of
a RLC circuit?
What is meant by resonance of an RLC
series circuit? Describe the properties of the
circuit at resonance. How is the
resonant frequency calculated?
