Practical Electronics/Series RC

Series RCEdit

A circuit of two components R and C connected in series

 

Circuit analysisEdit

Circuit's ImpedanceEdit

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 ResponseEdit

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
