A circuit of 3 components connected in series
Circuit's response
Equilibrium Response
At Equilibrium, the sum of all volatages equal to zero
The equation above can be written as below
With
Roots of 2nd ordered differential equation above
Resonance Response
The total impedance of the circuit
- At the total impedance of the circuit is Z = R . Therefore, current is equal to
- At , Capacitor opens circuit . Therefore, current is equal to zero
- At , Inductor opens circuit . Therefore, current is equal to zero
