Passive components: resistor, inductor, capacitor
Introduction
The passive components are of three types:
- the resistor
 - the coil
 - the capacitor
 
Utilization
The passive components are used in the Steady State AC Magnetic and the Magnetic Transient applications.
Characteristic
The current-voltage characteristic for each of these different components is mentioned again in the table below.
| Component | 
                         Current-voltage characteristic  | 
                     Characteristic quantity | Initial value | 
|---|---|---|---|
| resistor | 
                         | 
                     R is the value of the resistance in (in Ω ) | |
| coil | 
                         | 
                     L is the value of the coil inductance (in H) | 
                         Initial current I (t = 0)  | 
                  
| capacitor | 
                         | 
                     C is the value of the capacitance (in F) | 
                         Initial voltage U (t = 0)  | 
                  
where:
- U(t) is the voltage at the terminals of the component (in V)
 - I(t) is the current flowing through the component (in A)
