Phase Angle Difference Between Voltage and Current[edit | edit source]
There is a difference in angle Between Voltage and Current . Current leads Voltage by an angle θ
The difference in angle between Voltage and Current relates to the value of R , C and the Angular of Frequency ω which also relates to f and t . Therefore when change the value of R or C , the angle difference will be changed and so are ω , f , t
Natural Response[edit | edit source]
- ln V =
- T = RC
Summary[edit | edit source]
In summary, RL series circuit has a first order differential equation of voltage
Which has one real root
