Question

Impedance of l-r cicuit is

Answer 1

Explanation:

The impedance of series RL Circuit is nothing but the combine effect of resistance (R) and inductive reactance (XL) of the circuit as a whole. The impedance Z in ohms is given by, Z = (R2 + XL2)0.5 and from right angle triangle, phase angle θ = tan– 1(XL/R)
