Frequently asked questions
How is series RLC impedance calculated?
Z = √(R² + (XL - XC)²).
How are XL and XC calculated?
XL = 2πfL and XC = 1 / (2πfC).
What does a negative phase angle mean?
In this model, it indicates net capacitive behavior.
Is the current shown ideal?
Yes. It is calculated as I = V/Z using RMS values.
