We have seen the phasors
and time curves for the circuit elements in Series RLC AC
circuits. Now we can investigate the concept of resonance in
the same circuits. Resonance occurs when the overall impedence is the
lowest .. that means that XL is very nearly XC. That's the peak of the
graph.
Since the reactances' of the Capacitor
and the Inductor depend on the frequency of the generator, it seems
reasonable that the Power in the resistor will also depend on the
frequency.
You can change the parameters below, to
investigate the circuit characteristics, and your particular power for
your frequency (shown as blue dot on the graph). [Note: red variables
below change the size/shape of the curve!]
Set the initial parameters of the circuit :
Emax =
volts
R =
ohms
L =
Henries
C =
microFarads
f =
cycles/sec
Here are the equations we
will use ...
