5.8 MODELLING OF ELECTRICAL SYSTEMS

The basic element of a electrical system are (i) resistor, (ii) inductor and (iii) capacitor.

5.8.1 Resistor

 

From Fig. 5.19, we can write

 

 

Fig. 5.19 Resistor

 

v = i R       (5.24)

5.8.2 Inductor

 

From Fig. 5.20, we get

where v is voltage and i is current.

5.8.3 Capacitor

 

From Fig. 5.21, we can write
