Series RCEdit

Electric circuit of two components R and L connected in series

Circuit analysisEdit

Circuit's ImpedanceEdit

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 ResponseEdit

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
