Electronics/RL transient
For a series RL of one resistor connected with one inductor in a closed loop
Contents
Circuit Impedance[edit]
In Polar Form Z/_θ
 = R/_0 + ω L/_90
 Z = Z/_θ = /_Tan^{1}
In Complex Form Z(jω)
Differential Equation of circuit at equilibrium[edit]
Time Constant[edit]

t I(t) % I_{o} 0 A = e^{C} = I_{o} 100% R/L .63 I_{o} 60% I_{o} 2 R/L I_{o} 3 R/L I_{o} 4 R/L I_{o} 5 R/L .01 I_{o} 10% I_{o}
Angle Difference between Voltage and Current[edit]
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
