Impedance of an RL Series Circuit
This calculates the impedance when a resistor and a coil are connected in series.
| Impedance |Z| | Ω |
| Phase φ | ° (degrees) |

| \(\normalsize\\ \hspace{30px}Z=R+j\omega L,\hspace{10px}\omega=2\pi f\\ \hspace{30px}|Z|=sqrt{R^2+(\omega L)^2}\\\) |
＜Phase Difference＞
| \(\normalsize \hspace{30px} \phi =\tan^{\tiny -1}{\large(\frac{\omega L}{R})}\) |
