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+jXL
Here R is the resistance, and XL is the inductive reactance.
XL=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.
