Impedance (Z) vs Resistance (R)
Formel
## AC Impedance Impedance is the total opposition to current flow in an AC circuit, including both resistance and reactance. ### Formula **Z = sqrt(R² + (XL - XC)²)** where XL = 2*pi*f*L is inductive reactance and XC = 1/(2*pi*f*C) is capacitive reactance. The phase angle is **phi = arctan((XL - XC) / R)**.
Lösungsbeispiel
A series RLC circuit with R = 100 Ω, XL = 150 Ω, XC = 80 Ω.
- 01Z = sqrt(R² + (XL - XC)²)
- 02Z = sqrt(100² + (150 - 80)²)
- 03Z = sqrt(10000 + 4900)
- 04Z = sqrt(14900) = 122.07 Ω
- 05phi = arctan(70/100) = 34.99°
