11 RC AND RLC CIRCUITS IN TIME-DOMAIN
resonance is the condition under which the input impedance
(admittance) offered to the sinusoidal source is resistive.
Series RLC circuit is resonant at
ω
n
. At that frequency, the
impedance of the circuit is a minimum at R and is resistive.
Circuit draws current at unity power factor. Voltage across
capacitor and inductor will be of equal amplitude; but opposite
in phase. The voltage amplification factor at resonance will
be Q or 1/2
ξ
.
Parallel RLC circuit is resonant at
ω
n
. At that frequency, the
impedance of the circuit is a maximum at R and is resistive.
Circuit develops voltage at unity power factor. Current ...
