Formula & Methodology
The formula to calculate impedance (Z) in an RL circuit is:
Z = √(R² + (ωL)²)
where ω is the angular frequency (ω = 2πf).
Real-World Examples
Example 1
R = 10 ohms, L = 0.1 henry, f = 50 Hz
Z = √(10² + (314.159 * 0.1)²) = 10.049 ohms
Data & Statistics
| R (ohms) | L (henry) | f (Hz) | Z (ohms) |
|---|---|---|---|
| 10 | 0.1 | 50 | 10.049 |
| 20 | 0.2 | 60 | 20.094 |
Expert Tips
- Always use consistent units for better accuracy.
- Consider the phase angle for a more comprehensive analysis.
