Series RC[edit]

Electric circuit of two components R and L connected in series

Circuit analysis[edit]

Circuit's Impedance[edit]

In Rectangular coordinate

In Polar coordinate

The value of depend on the value of R and L . Therefore when the value of R or L changed the value of Phase angle difference between Current and Voltage , Frequency , and Angular of Frequency also change

Circuit's Response[edit]

Natural Response of the cicuit can be obtained by setting the differential equation of the circuit to zero

The natural reponse of the circuit is an exponential decrease
