Circuit analysis[edit | edit source]

Circuit's Impedance[edit | edit source]

In Rectangular coordinate

In Polar coordinate

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

Circuit's Response[edit | edit source]

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

The natural response of the circuit is an exponential decrease
