For a series RL of one resistor connected with one inductor in a closed loop
Circuit Impedance
In Polar Form Z/_θ
= R/_0 + ω L/_90
Z = |Z|/_θ = /_Tan-1
In Complex Form Z(jω)

Angle Difference between Voltage and Current
Voltage leads Current at an angle ? When a determining process is necessary many problems arise in a diagram. We need to expend on one process for the determing factor in this type of formulae
Tan? =
Change the value of R and L will change the value Angle Difference, Angular Frquency, Frequency, Time
