Impedance of LR Circuit is

Answer: B. √R²+(ωL)²

The impedance of the LR series circuit is Z=√R²+(ωL)²

Explanation:

The impedance of the LR series circuit is 

Z=R+jX_L

Here R is the resistance, and X_L is the inductive reactance.

X_L=ωL

⟹Z=R+jωL

⟹Z=√R²+(ωL)²

Hence,

The impedance of the LR series circuit is Z=√R²+(ωL)²

Option B is the correct answer.
